New description:
pkgver.hs:
{{{
{-# LANGUAGE CPP #-}
main = print PACKAGE_VERSION
}}}
PACKAGE_VERSION is expected to be a quoted string.

Issue seen in the wild thanks to cabal -w flag. Building darcs with "cabal
install darcs-2.4 -w ghc-6.10.4.exe" fails.
Affected 6.10.4 and 6.12.1. More info here:
