The Cinelerra community version has to be checked out from a
Subversion repository.

You can get the latest commit with:

svn checkout svn://svn.skolelinux.org/cinelerra/trunk/hvirtual

After the checkout has finished, see what revision SVN indicated and 
rename the hvirtual/ directory to cinelerra-cv-revisioncl_number.
For example this checkout what revision 1009, so the hvirtual dir 
was renamed to cinelerra-cv-r1009:

mv hvirtual cinelerra-cv-r1009

Then tar it and bzip it to save space:

tar cvf cinelerra-cv-r1009.tar cinelerra-cv-r1009/
bzip2 cinelerra-cv-r1009.tar

Also make sure you install libraw, libiec, libavc, openexr 
and libdv before trying to compile cinelerra.
Otherwise the configure script warns that some vital components
are not installed, but blunders along and creates the Makefiles anyway
which are useless because gcc eventually fails to compile everything.

The doinst.sh script here has a little extra in it to make cinelerra
work correctly on first-start. the symlink info will be pre-pended
to it by makepkg.
