I obviously failed to communicate that this is a problem with GHC, _NOT_ 
with Darcs. GHC needs a properly installed version of readline to work 
correctly, and of course, without a working GHC you can't compile Darcs.
GHC is looking for readline.h and history.h, which should be located 
under /usr/include/readline/ or /usr/local/include/readline. The RPM for 
GHC is supposed to have checked that these files are available, but it 
might have missed it. Check to see that the files are there. If not, you 
will have to download readline and install it. Then try compiling Darcs 
again.
You should probably also upgrade to ghc 6.2.2 if you can, it contains 
many bugfixes. Also, what operating system are you running?
