--------------------------------+-------------------------------------------
Because of another software package, I had previously installed gnu
 readline 5.1 in /usr/local.  In order to build ghc 6.6.1, I first
 installed the pre-built version of 6.6 and during that installation there
 was a message about replacing the system readline as part of the install
 (alas, I forgot to write down the exact message).  When I ran make after
 configuring 6.6.1, the haskell library readline function didn't compile,
 and the make aborted when a later step couldn't find readline to build the
 libraries.

 I tried again with a freshly unpacked source directory but after
 reinstallng gnu's readline first, and the build appears to have completed
 successfuly this time.

 So something isn't quite right in the way that readline is handled, either
 because 6.6 deleted something that it shouldn't have, or the build is very
 sensitive to where readline is and has problems if there is a copy in
 /usr/local, or some other reason.

 Of course this is less important now that a pre-built 6.6.1 is available
 on the web site, but it would be nice to clean up if possible.
