I don't have a Mac, but I seem to recall discussion about some compilers
needing to be told that it is OK to reference global variable declarations
from other compiled modules. Your error message looks as if it might be
that sort of problem. Of course you can just exclude this plugin from the
build as a quick workaround (feed --without-Mpeg3Plugin to the configure
script I think).
