For some reason, I have Haskell installed on my machine. I'm pretty new
to Linux and Debian - I've been running it for about 6 mo now without
too much trouble. Now every time I try to use apt or aptitude, I get
error messages. For example:
legner1:~# apt-get upgrade
Reading package lists... Done
Building dependency tree... Done
You might want to run ‘apt-get -f install’ to correct these.
The following packages have unmet dependencies.
libc6-i686: PreDepends: libc6 (= 2.3.6-7) but 2.3.6-15 is installed
mysql-client-5.0: Depends: libmysqlclient15off (>= 5.0.22-3) but it is
not installed
Depends: libmysqlclient15off (>= 5.0.19-1) but it is not installed
mysql-server-5.0: Depends: libmysqlclient15off (>= 5.0.19-1) but it is
not installed
php5-mysql: Depends: libmysqlclient15off (>= 5.0.19-1) but it is not
installed
Depends: php5-common (= 5.1.4-0.1) but 5.1.2-1 is installed
E: Unmet dependencies. Try using -f.

So I tried their first recommendation:
legner1:~# apt-get -f install

I also tried the 'apt-get -f upgrade' approach, and after about 2 hours
of downloading I got this:

It seems like this c2hs and ghc-pkg issue is causing a bottleneck. How
does one go about solving such a dilemma? Can I manually get rid of
Haskell & company?
