Well, that's really the whole point of my email.  Probably very
clumsily asked though.

Yes, GHC 6.12 provides utf8-string 0.3.4, neither xmonad-contrib nor
haskell-x11-xft rely on any particular version (anything >=0.3
satisfies both).  Yet pacman installed haskell-utf8-string (0.3.6).
It looks like pacman didn't take into consideration that ghc (the Arch
package) provides haskell-utf8-string[1].  In other words, it looks to
me like pacman's dependency resolution has a bug.  With my usual doubt
in my own abilities I was wondering if there isn't a fault in my logic
