gdb was already installed, so it didn't actually do anything.

MacPorts does a sanity check after any install or upgrade, to look for
anything (not just the port you installed/upgraded) that is broken for some
reason:

Older versions of various ports using openmpi had a bug where they thought
they could specify it along with a compiler; in fact, openmpi requires that
the same compiler be used everywhere and acts like a compiler itself. The
fix for this is

    sudo port upgrade --enforce-variants arpack +accelerate+openmpi

(note lack of +gcc47, which was the bug).
