Just to be clear, the --build switch needs to be added to the 
CONFIGURE_ARGS in the port Makefile, not set on the commandline
the way I show it above.

There's also a typo above: the arg I actually used was
"powerpc" with only two p's.
I haven't tried it with ${ARCH} but that should work too.

I found I also needed to add the --enable-shared switch in order
for the pkg-static steps of the install to succeed.  For some reason
the shared libs weren't being built without that switch and I got
error messages about them not being found.

I'll submit a PR once I've got everything up and running on the mini
and can include a diff and the usual machine info.

Thanks for your help!
