This small modification cuts off about 25% off pkg_version on my system.
Basically bsd.gnome.mk recursively finds all the dependencies, but many
of them are listed many times. This makes make work extra hard when it
doesn't have to. I simply weed out the repeated entries.

Be careful, != assignments may add thousands of process invocations to
large targets like 'make index' and can slow it down dramatically.

Thanks for the warnings. It turns out that this can be done without
"!=", but even if this were not the case, I think that in this situation
the savings would definitely outweigh the costs. For example, this
dramatically improves the time for invocations of "make -V PKGNAME" for
deskutils/alacarte (on my system from about 1.5 seconds to .3 seconds).
It only affects a few ports, but enough, I think, to increase the speed
of "make index" noticeably albeit not dramatically.
