Background: I'm an experienced Linuxer, but not experienced with the Debian package-management tools. I recently decided it was time to renew my acquaintance with Haskell, which began before the do-notation, with Hugs. Seeing the warnings on the ghc website, I decided to install a Linux distribution with a strongly checked package system. I chose Knoppix-7.2.0 i386 (the latest, dated mid-2013), which installed with few problems (now fixed). It claimed to be based on wheezy, the stable branch. Even though the version of haskell-platform in wheezy/stable was from mid-2012, I presumed it would be debugged by now - after all, that's what "stable" is supposed to mean. So I hooked it up to the net, and entered apt-get install haskell-platform After a few seconds, it said that there were broken packages - I think they were libglut-dev and libgl-dev - and that it couldn't fix them. Aptitude, which has a menu-item called 'fix broken packages', couldn't fix them, either. If I recall correctly, there were intrinsically unsatisfiable version constraints, i.e. >=V and <V for the same V. So my question is: have I somehow introduced this (I re-used a knoppix-data.img without ensuring it was empty) or is the problem upstream from me? (i.e does anyone else have this problem?) Looking at the open bug list for haskell- package, I can't tell whether it's a recognised bug. Subsidiary question: since I would prefer to spend time on Haskell rather then on the package system, would it be quicker (in days, not in milliseconds :-) to use nhc98 or Hugs98-Sep2006, obsolete though they are?
