After having a closer look at the configure script, it looks like the
compiler options you're using are the vanilla options obtained by a
simple ./configure.

Now, maybe you could add "-mpim-altivec" to your config.mak, that may
do the trick.

If it doesn't do the trick, please run "make clean ; ./configure ; make"

and post the content of your console
