Hi Joachim,
Happy New Year and thanks for your mail.
Sorry for my slow reply: I was busy rebuilding
Fedora packages for haskell-platform-2011.4...

Yes - probably mostly I have "stolen" your patches. :-)

Right - perhaps I can take a stab at it one day if noone else has time.
Yes this patch is probably the main maintenance burden currently for ghc
so it would definitely be good to upstream - perhaps it needs a switch
in configure though or Linux should just use system libffi anyway.
(Though earlier when I proposed the latter to SimonM, he was not too keen.)

I see thanks. Ok I will definitely consider that.
So with that you don't see any lag with installing haddock documentation
any more, or probably debian spawns a subprocess for re-indexing anyway?

Ok, I will try to do a testbuild of rc1 for Fedora finally soon too.

Yes thanks. Likewise for our Fedora haskell-devel list though
probably it is currently a bit too noisy with bugzilla mail traffic.
Actually I was wondering if it would make sense for us to
setup a Haskell distro mailing-list for people involved/interesting
in packaging haskell for Linux to communicate about issues?
Perhaps even packaging for all platforms? What do you think?
Thanks for reaching out and also I would like to say thanks and my respect
for the great work Debian has done and continues to do on Haskell packaging.
Jens
