Comment (by ryandesign at macports.org):

 Anders, you're awesome. That seems to fix it.

 My remaining concern is that everywhere we want to unset environment
 variables now, we have to call two procedures. Can there be a single
 procedure that takes care of everything we need? Do we still need "`array
 unset env`" now that we have "`unsetenv`"? If we do still need both, then
 it would be good to have a wrapper function which we can call which itself
 calls both of those.
