I cannot reproduce this. I tried on the community server which is debian 4.0 (which I think is etch right?). It was using ghc-6.6. I tried with Cabal-1.4.0.1 and bimap from hackage.
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)?
No, that should be fine. It's parsing a Version so that can be any sequence of digits separated by dots.
By the way, compiling the Setup.lhs-file of bimap and running it does work:
jochem@huygens:/tmp/bimap-0.2.2$ ghc --make Setup.lhs -o Setup [1 of 1] Compiling Main ( Setup.lhs, Setup.o ) Linking Setup ... jochem@huygens:/tmp/bimap-0.2.2$ ./Setup configure Configuring bimap-0.2.2... jochem@huygens:/tmp/bimap-0.2.2$
That's pretty weird. Are you sure ghc and runghc are the same version? Duncan
