In fact, I think I just nailed it:
===>  Building package for iiimf-csconv-r11.4
Creating package /usr/ports/packages/All/iiimf-csconv-r11.4.tgz
Registering depends:.
Creating gzip'd tar ball in '/usr/ports/packages/All/iiimf-csconv-r11.4.tgz'

FreeBSD menelaos.informatik.rwth-aachen.de 4.9-STABLE FreeBSD 4.9-STABLE #15: Thu Mar 25 15:34:34 CET 2004     root@menelaos.informatik.rwth-aachen.de:/usr/obj/usr/src/sys/MENELAOS  i386

The port uses threads, and you'll see many incarnations of
"cc .. -pthread -lc" which really strain the eyes.
Stripping the "-lc" from the configure-script seems to do the trick.

I'll submit a patch once I cleaned up.
