I initially (and erroneously) posted this to bug 128659. Emerge cinelerra-cvs was failing at filedv.C. I upgraded to libdv 104-r1 and it compiled fine so I guess the dependency just needs to be updated.
Current cvs.cinelerra.org checkout now requires libDV >=0.103. Ebuild with this included attached to bug 128659.
This has been fixed in the latest ebuild (cinelerra-cvs-20060619) Thanks for the bug report! Cheers, Marc.
