Johannes,

Thanks for the reply and I'm sure you are right but I'm still stuck with
knowing what to do about it.

I think I have a readline:

> dom at lagrange:~/ghc> ls /usr/include/readline/
> chardefs.h  keymaps.h   rlconf.h  rltypedefs.h
> history.h   readline.h  rlstdc.h  tilde.h

I couldn't see anywhere on
http://hackage.haskell.org/trac/ghc/wiki/Building/Hacking where it
mentioned readline.

Ok I can see in config.log that I don't have editline. That sounds very
suspicious. Mind you I'm not sure where to get it from for opensuse.
I'll have a hunt around.

Dominic.
