missing math functions on powerpc (macppc)?

["John D. Baker" <jdbaker%mylinuxisp.com@localhost>]

Trying to update "multimedia/ffmpeg010" on macppc-current (7.99.24)
fails when it claims the libvpx version is insufficient, despite
the prior dependency discovery:

If you think configure made a mistake, make sure you are using the latest
version from Git.  If the latest version fails, report the problem to the
ffmpeg-user%ffmpeg.org@localhost mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solving the problem.

I'm wondering where the problem actually lies as "/lib/libm.so" has all
the symbols being complained about.  Was libvpx somehow built incorrectly?
