sure, your not missing any system libraries and using right version of 

libraries required by RhodeCode. There's also restriction in terms of mercurial

clients. Minimal version of hg client known working fine with RhodeCode is

**1.6**. If you're using older client, please upgrade.

Installing RhodeCode from Cheese Shop

-------------------------------------

Rhodecode requires python version 2.5 or higher.

The easiest way to install ``rhodecode`` is to run::

    easy_install rhodecode

Or::

    pip install rhodecode

If you prefer to install RhodeCode manually simply grab latest release from

http://pypi.python.org/pypi/RhodeCode, decompress the archive and run::

    python setup.py install

For installing RhodeCode i highly recommend using separate virtualenv_. This

way many required by RhodeCode libraries will remain sandboxed from your main

python and making things less problematic when doing system python updates. 

- Assuming you have installed virtualenv_ create a new virtual environment 

  using virtualenv command:: 

    virtualenv --no-site-packages /var/www/rhodecode-venv

.. note:: Using ``--no-site-packages`` when generating your

   virtualenv is **very important**. This flag provides the necessary

   isolation for running the set of packages required by

   RhodeCode.  If you do not specify ``--no-site-packages``,

   it's possible that RhodeCode will not install properly into

   the virtualenv, or, even if it does, may not run properly,

   depending on the packages you've already got installed into your

   Python's "main" site-packages dir.

- this will install new virtualenv_ into `/var/www/rhodecode-venv`. 

- Activate the virtualenv_ by running::

    paster make-config RhodeCode production.ini

- This will create the file `production.ini` in the current directory. This

  configuration file contains the various settings for RhodeCode, e.g proxy 

  port, email settings, usage of static files, cache, celery settings and 

  logging.

Next, you need to create the databases used by RhodeCode. I recommend that you

use postgresql or sqlite (default). If you choose a database other than the

default ensure you properly adjust the db url in your production.ini

configuration file to use this other database. RhodeCode currently supports

postgresql, sqlite and mysql databases. Create the database by running

the following command::

    paster setup-rhodecode production.ini

This will prompt you for a "root" path. This "root" path is the location where

RhodeCode will store all of its repositories on the current machine. After

entering this "root" path ``setup-rhodecode`` will also prompt you for a username 

and password for the initial admin account which ``setup-rhodecode`` sets 

up for you.

- The ``setup-rhodecode`` command will create all of the needed tables and an 

  admin account. When choosing a root path you can either use a new empty 

  location, or a location which already contains existing repositories. If you

  choose a location which contains existing repositories RhodeCode will simply 

  add all of the repositories at the chosen location to it's database. 

  (Note: make sure you specify the correct path to the root).

- Note: the given path for mercurial_ repositories **must** be write accessible

  for the application. It's very important since the RhodeCode web interface 

  will work without write access, but when trying to do a push it will 

  eventually fail with permission denied errors unless it has write access.

You are now ready to use RhodeCode, to run it simply execute::

    paster serve production.ini

- This command runs the RhodeCode server. The web app should be available at the 

  127.0.0.1:5000. This ip and port is configurable via the production.ini 

  file created in previous step

- Use the admin account you created above when running ``setup-rhodecode`` 

  to login to the web app.

- The default permissions on each repository is read, and the owner is admin. 

  Remember to update these if needed.

- In the admin panel you can toggle ldap, anonymous, permissions settings. As

  well as edit more advanced options on users and repositories
