The Film Gimp in CVS at film.gimp.org was used as a snapshot for SiyrceForge version 0.1. Do not checkout the version at film.gimp.org with the expectation that it will be up to date with the current source tarball maintained on SourceForge.
There is no Film Gimp CVS presently on SourceForge simply because I think CVS can be more trouble than it is worth. My preference is releases and patches. However, if there is demand from developers for CVS we will provide it.
For historical interest, below are the instructions for checking out the version of Film Gimp kept at film.gimp.org. We have no control over what's there. Administrative obstacles there were a motivation for moving to SourceForge.
The Film Gimp branch is named HOLLYWOOD.
$ cvs -z3 -d:pserver:anonymous@gap:/cvs/gnome checkout -r HOLLYWOOD gimp
This command illustrates accessing CVS from behind a firewall named 'gap' that has its port 2401 pointing to the server anoncvs.gimp.org. If not behind a firewall specify anoncvs.gimp.org in the cvs checkout command rather than gap.
After the 18mb download from CVS is completed you will have to make some changes to build. In gimp/plug-ins/Makefile.am delete rll, pts, fm_pts, parsley from the list of directories included in the SUBDIRS variable there. These plug-ins will not build in Film Gimp and would cause the build to fail. The pts plug-in is a proprietary Rhythm & Hues asset manager, and rll is the format they use for images.
$ cd gimp
$ libtoolize --force
$ aclocal
$ automake
$ autoconf
$ ./configure -prefix=/usr/local
$ make
$ ./app/gimp
