There seems to be some linuxisms in the Makefile and configure, it
won't compile on Mac OS X (or FreeBSD for that matter). At a glance,
there's at least two portability issues because the BSD version of cp
doesn't support "-a", the ld option for Mac OS X to create bundles is
not "-shared".

I wasn't saying that there are no good regexp implementations
available for Erlang, just that the one in stdlib isn't very
interesting. The stdlib is where I imagine most (new?) people are
going to look for functionality, because jungerl is a mess and
erlrt/REPOS/whatever isn't ready yet.
