Matthew,
Jacob is correct that your problem is related to the missing
dependency. You're getting that error because chameleon is falling
back to code that loads the module when it doesn't find it available
to php. dylib is the shared library extension that php picks up from
OS X. The best solution is to reconfigure and rebuild php with
--enable-dbase.
If you don't want to do that, you might find this page helpful:
