We had a discussion on glasgow-haskell-users recently about whether to use 
libtool, and the general concensus was not:

Partly my fault for sloppy reviewing, sorry about that.  I was under the 
impression that this only affected dynamic linking so it wouldn't break 
anything.

Clemens, shouldn't we only be adding -rpath when -dynamic is on?
