ghc in my sid (debian unstable) chroot gave "6.8.2". Maybe Cabal 1.4
doesn't like versions of the form x.y, only of the form x.y.z (wild
speculation)?

By the way, compiling the Setup.lhs-file of bimap and running it does
work:


jochem at huygens:/tmp/bimap-0.2.2$ ghc --make Setup.lhs -o Setup

jochem at huygens:/tmp/bimap-0.2.2$ ./Setup configure

jochem at huygens:/tmp/bimap-0.2.2$
