I suspect that GHC isn't looking in /usr/local/include for include
files.  Adding -I/usr/local/include might help.  A better fix is to
modify the package configuration for the util package to add
"/usr/local/include" to the list of include_dirs.

Nobody's fault, really: the GHC package you installed was simply built
on a system that had the readline headers installed in a different
place.
