Threading library changes are a good reason to rebuild your ports in

You can only use it on 7.x if you add compatibility libraries and ensure
your kernel has COMPAT_FREEBSD6 in it. These libraries have given some

all ports from scratch (pkg_delete -af please) when upgrading between
major FreeBSD versions (e.g. 6.x -> 7.x).
