I am surprised you didn't hit the error with the linux/cdrom.h before that
too. The libmpeg3 package has several patches that remove the Linux
support. I have updated to libmpeg3-1.5.4 in my personal pkgsrc, but I am
still testing. There is no maintainer for this libmpeg3 package. I noticed
these problems because I wanted to install transcode.

As for your ffmpeg issues, please see my PR pkg/28915: ffmpeg on Linux
needs -ldl. http://www.NetBSD.org/cgi-bin/query-pr-single.pl?number=28915
(ffmpeg also has problems with ffplay under Linux and NetBSD-reference in
manpage.)
