I've build it, and it's available at:
http://debian.holoscopio.com/ghc6 .

I've got some problems with trying to remove some old packages after
installing ghc6-6.10.

(Reading database ... 142593 files and directories currently installed.)
Removing libghc6-svgcairo-dev ...
Removing libghc6-cairo-dev ...

Errors were encountered while processing:

 libghc6-mtl-dev
E: Sub-process /usr/bin/dpkg returned an error code (1)
A package failed to install.  Trying to recover:
Press return to continue.

I think the problem here was that the package was installed with dpkg
-i, and the other were not removed before ghc6.  A solution to this
would be not to exit with an error from prerm when this kind of thing
happens, maybe using || true in the call to ghc-pkg.

What do you think?

Greetings.
