Mac OS X build problems

First of all I think you guys are doing a great job.  I've been
looking for an alternative to Easysoft's uber expensive solution for a
while now.

I'm having build problems on Mac OS X.  I trield building from CVS and
autoconf takes a dump on me, so I backed down to 0.6pre1 and the build
fails:
