Yes, that is a bit annoying.  The readline issues are mentioned on the
download page though -- you were warned ;).  GHC 6.6.1 is only a day
old, so there aren't very many binary builds available.  On the other
hand, GHC 6.6 has RPMs for FC5:

Please don't make generalizations from a single experience with a
compiler version that is less than a day old.
