This was a temporary build bug yesterday that is now fixed, sorry for the

Re: Linker error when building GHC HEAD on Mac OS

[David Kirkman]

It looks like you're running into the problem of apple's readline
not actually being readline at all (it's a link to some other library
that is almost, but not quite, readline).

See http://cvs.haskell.org/trac/ghc/wiki/Building/MacOSX
for instructions on how to install readline and how
to tell ghc where it is.

I've successfully built HEAD (Feb 25) on ppc OS 10.4.8, so
I know it will work.  But I also remember it took me a half
dozen tries to get it to build the first time (mostly related to
this readline business!)
