>Description:
multimedia/x264-devel doesn't build n NetBSD 3 because it's math library lacks 
the log-base-2 functions, in particular log2f().
>How-To-Repeat:
On a 3.x system, cd multimedia/x264-devel && make build
>Fix:
Patch the configure script to detect log2f() presence and emulate it via log() 
if not present?
