Can't create sdist bundle

[Neil Mitchell]

Hi,

Long time problem, now with a new version of GHC and Cabal, and still
a problem...

C:\Documents\Uni\uniplate>runhaskell Setup sdist -v3

late-1.0.1"])
C:\bin\tar.exe: Cannot use compressed or remote archives
C:\bin\tar.exe: Error is not recoverable: exiting now

Calling tar then gzip would make this work. This bug stops me from
updating my Hackage packages which won't work with GHC 6.8.1.

Thanks
