These instructions have been tested on Ubuntu.
Symbiota provides some excellent documentation for the download/configure/install process:
System requirements: Establishing a Node.
Download and install instructions: Installation Steps.
Prerequisite: Subversion command-line client
Obtain Symbiota's source code from SourceForge by doing an svn export of the trunk.
> svn export https://symbiota.svn.sourceforge.net/svnroot/symbiota/trunk/ symbiota > cd symbiota
To avoid some xml error messages in Eclipse, obtain and apply symbiota-fp.patch:
> cp /path/to/symbiota-fp.patch . > patch -p0 < symbiota-fp.patch
This process is thoroughly documented on Symbiota's web page (see above link) and in a README.txt file that is included when you check out the project from the repository.
However, there is one thing missing. Among the template files that you must copy, css/jquery-ui_template.css is not mentioned. Be sure to copy that to css/jquery-ui.css.
