* Whether you link statically or dynamically against a GPL'ed library does not make any difference as far as your legal obligations are concerned.

This statement is something that the FSF would *like* to be true. It is not clear that it *is* true. In particular, if you dynamically link with a GPL library but NEVER distribute that library, you may not be obligated under the GPL. The issue arises from the fact that the GPL gains its teeth when you distribute GPL code, not when you use it. The advice I have received is that this is a gray area where the FSF would have to work exceptionally hard to win a suit.

Yes, that makes sense. Besides, we are not trying to get around the FSFs intention by linking non-free code with GPL code - GHC is perfectly fine free software according to the FSFs own definition <http://www.gnu.org/philosophy/free-sw.html >. So, they probably couldn't care less.
