Yesterday there was an update to haskell-x11 available (1.4.6.1) and pacman was happy with installing it. GHC however, was not since a few of the other installed packages depended on version 1.4.5. Despite ghc-pkg complaining loudly pacman pushed on and in the end I was left with a somewhat broken system.
To fix it I ran "pacman -Rcs haskell-x11", but that of course means I can't use xmonad until it has been recompiled against the newer haskell-x11.
AFAICS this all stems from xmonad having the dependency on "haskell-x11" when it in fact ought be on "haskell-x11>=1.4.5 haskell<1.4.6".
Is it possible to get these more specific dependencies into PKGBUILDs in some automated fashion, so that breakage like this can be easily avoided?
Ah, so the binary xmonad has more precise dependencies than the src xmonad -- so when cabal2arch generates a PKGBUILD -- one that works for AUR -- it will actually be subtly broken for the binary installs, where the ABI compat requires only one version of each dependency. I think we could do this -- it would be done when moving a PKGBUILD into the binary repos -- and pinning the version at that point. -- Don
