Description

#if defined(freebsd) || defined(openbsd)
      err = (char *)dlerror();
#else
      err = dlerror();
#endif

Why is this #if dance necessary here?

http://www.freebsd.org/cgi/man.cgi?dlerror dlerror() hasn't been const char* since FreeBSD 8.1. In OpenBSD it's still is ...broken, but then we should abstract that into a wrapper function of our own at autoconf time.

We're not handling this case at every call of dlerror() anyways.. so....
