I agree with Yenthe.  Also, Odoo does not state this.  In fact, they state the opposite.  This is what Odoo writes about installing from source:

Harder to get started than Packaged installers, provides even greater flexibility: packaged installers don't generally allow multiple running Odoo versions on the same system, and don't provide easy source access to Odoo itself.

Good for developing modules, can be used as base for production deployment.

The source code can be obtained by downloading a tarball or using git. Using git is strongly advised, as it makes it easier to update, switch between multiple versions (including the current development version) or contribute.
