My guess is that the problem is because gcc42 is involved with an older
FreeBSD.  RELENG_5 uses gcc 2.95.2 by default, while RELENG_6 uses gcc
3.4.6.  RELENG_7 uses 4.2.1.  Therefore, I'm betting that when you use a
non-native gcc on an older platform, it *expects* you to rely on libgcc
(which is a shared library) to gain access to all of the functions which
are missing.

Is gcc 4.2 really required for that port to build?
