It has slightly more licensing complications - GMP is LGPL, which 
requires that the user of a program that includes it be able to replace 
GMP. Shared libraries do that easily.  Static linking would probably 
require someone who compiles+distributes a program that uses both 
Haskell and GMP/MPFR to distribute their .o files (or alternatively 
their source code), so that they can be re-linked to a different GMP. 
(Their program still does *not* have to be LGPLed.)

The parties I've heard publicly concerned about duplicate packages are 
Linux/BSD distros that primarily support Free Software.  So that 
complication might not even be a problem (provided the GHC user would 
get a choice whether to staticly link, and probably default to dynamic 
linking).
