But my point is that aclocal on Mac OS X (or maybe just the Mac
package manager you're using) is broken.  What does 'aclocal
--print-ac-dir' print out?  It sounds as if you need to fix your
aclocal, or if you can't do that, set ACLOCAL_PATH for your
environment only.  No one else has /opt/local ...
