Ok, so once again I have tried to compile/install leksah (http://hackage.haskell.org/package/leksah) with Haskell when using cabal2arch, and just after the package is 'built' (but not yet finalized) I get this error message

Doing a google search, I found that this error has occurred in other places, but only in build log fails for hackagedb packages

Note that the .cabal file for Leksah (incorrectly) has enable-shared one of the ghc build options, this needs to be removed for the package to build correctly (up until this error anyways); as well as the issue outlined below  (see http://answerpot.com/showthread.php?2552829-Build+error+with+lekash+on+archlinux+when+using+cabal2arch for more info). I have attached a correct PKGBUILD/.install file in this email

There also seems to be another error with cabal2arch, that puts the dependency haskell-leksah within the actual haskell-leksah package (of the same version as well) inside the PKGBUILD. I just removed that dependency from PKGBUILD to build leksah
