Do you have the libedit-dev package installed? If not, the editline backend may not have been built. You can check whether it was built by running ghci from a command prompt and checking whether the arrow keys work.

I forgot to mention that I was running the binary package -- didn't bother to build ghc from source. Because the binary package relies on libedit.so.0 and Debian only comes with libedit2, I created a symbolic link for libedit.so.0 pointing to libedit.so.2. Could that be a problem for Emacs? But the libedit backend works fine when running ghci from a command line. Thanks, Wei
