Development versionIf you have CVS and Perl installed, you can compile the very latest version of GDIS yourself by typing:
cvs -d:pserver:firstname.lastname@example.org:/cvsroot/gdis login
Hit enter at the password prompt, then type:
cvs -z3 -d:pserver:email@example.com:/cvsroot/gdis co gdis
which should create a folder called gdis containing all the source files.
Enter the gdis subdirectory and run the install script, which should automatically compile gdis based on your preferences.
It should also inform you of missing libraries that must be installed.
