Run ldd on libvpx.so.  It should have been linked with the math library
itself.

on netbsd-6 i386, I get:

/usr/pkg/lib/libvpx.so:
	-lm.0 => /usr/lib/libm.so.0
	-lgcc_s.1 => /lib/libgcc_s.so.1
	-lc.12 => /usr/lib/libc.so.12
	-lrt.1 => /usr/lib/librt.so.1
	-lpthread.1 => /usr/lib/libpthread.so.1

Surely libm on macppc must have those symbols, but you could check that
too.
