I eventually gave up on this end (because it wasn't working), and installed it via macports.org, and everything is working fine now. =)
Dave, sorry we had a race condition on our posts.Regex compiles for me with a straght 'configure', 'make', and 'sudo make install'. I don't use "-with-libraries=regex", I just build everything and let it install in the default /usr/local tree. However, while the dynamic libs install with the right permissions, on my systems (Mac Pro 10.5.2 and MacbookPro 10.5.2) the static libs end up 'rw' for root only so I do this afterwards to fix that:
"sudo find /usr/local/lib -regex '.*\.a' -exec chmod 666 {} \;"
