I knew this looked familiar ! It's the dreaded Debian/Global Local
conflict problem.  Some packages which I can't install using cabal I
install Debian packages for, which install globally.  Then, naturally,
there are Debian packages which won't install (running unstable :-) so
I used cabal for those and they install locally.  I thought it would be
better to keep it local to avoid conflicts, so much for that theory.

I basically use Debian for two reasons: to get ghc and to get cabal.
After that it seems to me a better idea to stick with cabal rather than
the debian packages.

Well I know what I'm doing this  weekend :-)

Thanks very much (everyone) for the help.
