I'll be looking at making it optional once 6.8.1 is out of the way, but
you will need to use a GHC compiled with an alternative; you won't be
able to make a non-GMP program with a GMP GHC.

Readline isn't, but is already optional, and won't get linked into
programs you write unless you actually use it.
