Unfortunately Yhc is not that well maintained or usable - the GHC compiler is a lot more robust. If you want to work through something like YAHT with two compilers, I'd recommend Hugs and GHC.
Hi Neil I was under the impression that the Yhc was still being developed, although the repo has no patches for the last few months. What's its likely future? The reason I was looking at Yhc is that in the long run (aka when I get time) I'd like to learn more about compilers and virtual machines. So I'm using GHC to learn Haskell because I know it will work, but my interest was in Yhc as project rather than just a Haskell compiler. Yhc looks a lot more approachable (I think GHC is something like 100kloc?) and there's already some work done to make it compile to other environments, so I figured it'd be more fun to hack. Would Yhc be suitable for my learning purposes or could you recommend something else?

Weird. I will check this one out - sounds very suspicious.
Looks like the patch file is just plain missing.

It looks like you are building on Mac, which I know people have had difficulty with in the past. I'm not sure if anyone has figured it out yet?
Yeah - I'm using OS X 10.5. I could try it in a FreeBSD or Linux VM, although if the cpphs repo is unavailable I don't suppose I'd have much luck. Incidentally I did try replacing the cpphs darcs repo with an unpacked tarball source[1], but that doesn't help. It's also interesting to note that cpphs (version 1.3) is in MacPorts and compiles fine. I haven't looked at it further, I simply carried on working with GHC alone.
