As was already pointed out, ports do not compile with make -j X by
default. You can do so for ports that will build cleanly (not all of
them will), by adding something similar to the following to your

.if ${.CURDIR:M*/ImageMagick*}

A while back I found which ports I had installed that would play nice
with make -j, so I updated make.conf with a bunch of similar entries
to the above. Works fairly well, and there are actually quite a few
ports that will compile with make -j. If you're interested, let me
know and I'll throw my make.conf up somewhere.
