Yes, I'm familiar with this particular changeset- I wrote it. =)
Unfortunately, I can't reproduce this locally- neither with
devel/cmake nor any of the other ports that I build.  I think we'll
have to wait until either we get more reports of this or portmgr@
trips over it in a way that I can reproduce and dig in a bit.

Thanks,
