Fetch dependencies are installed before the fetch phase, but build and lib dependencies aren't necessarily installed until just before the configure phase.

It's not documented, and it's not something every port should be using, but when you need to know this information, then it's probably better to use the API than to run a shell.

I've fixed this in r92582, and made a few other adjustments to postgis2 in some earlier revisions.
