Segfaults on FreeBSD

[atmail.dreamhost.com]

Every now and then I try to get MacPorts to build and run on FreeBSD.

Getting it to build requires less than a handful of edits.

However, when running portindex I get a Segfault with a Signal 11.

Here’s what gdb says (after recompiling with debug symbols enabled)"

[marius at mars /opt/local/var/macports/sources/github.com/macports/macports-ports]# portindex
