 Thanks to Paul R Brown for the following [http://mult.ifario.us/articles/2006/10/17/ghc-6-6-and-mac-os-x-readline-quick-fix instructions].
 
-Building GHC 6.6 out of the box on MacOS X will leave you with a GHCi binary that has no readline support.  This is because MacOS X comes with a cut-down readline library that doesn't support all the things that GHC requires, so the GHC configure script decides not to use it.
+Building GHC 6.6 out of the box on MacOS X will leave you with a GHCi binary that has no readline support.  This is because MacOS X comes NetBSD's libedit and Apple has made /usr/lib/libreadline.dylib a symlink to libedit. libedit does not support all of the libreadline API that GHC requires, so the GHC configure script decides not to use it.

+ghc 6.6 can be built from source using [http://macports.org MacPorts] on Intel and PowerPC Macs.
