Hrm. The bug that Arthur Baars refers to has definitely been fixed in
GHC 6.0.1; I can't reproduce your problem here, everything works fine.
Where is the libreadline.dylib file installed, and what version of
readline is it?
You should be aware that if libreadline.dylib is installed when you
build GHC, the GHC binary itself will depend on it, so you'll need to
include a readline binary. I always made sure that I only had
libreadline.a while you're building GHC, so I could refrain from making
a libreadline distro, too.
Cheers,
Wolfgang
