Cannot update entire system

Hello, I haven't booted my machine for at least 2 months now.  When I brought it back up, I figured that it would be a good idea to update it.  When I tried doing that, this is what I got:

# pacman -Syu
:: Synchronizing package databases...
 core is up to date
 extra                                                     1810.6 KiB   131K/s 00:14 [################################################] 100%

Is there any way to install thse inter-related packages and have then include one another in their own ways?  What else can I do?

The dependency cycles look all right to me.

This bit is the problem. I think this news post might give you guidance on how to solve the haskell problem.

Hmm... how bizarre.  I didn't know I had that library.  Oh well.

I got around the problem by removing it entirely.

Re: Cannot update entire system

Check pacman log to see when exactly did you last update.

haskell-zlib is not in the repos, maybe you've installed it from the unofficial haskell repo or from the AUR https://aur.archlinux.org/packages/haskell-zlib/ . Remove the package, update your system and rebuild it form the AUR.
