[darcs-users] buildbot slave admins - please install maybench

[Eric Kow]

Hi,

I'm adding Duncan Coutts to this message in case he has other advvice to
give.  It looks like the cabal-install bootstrap script was not made
with GHC 6.6 in mind.

Thanks for being such a good sport about this.  So the cabal-install
dependencies are Cabal, HTTP and zlib.  Do you know which subset of
these installs painlessly on GHC 6.6?

The bootstrap script should have already downloaded
http://hackage.haskell.org/packages/archive/Cabal/1.4.0.2/Cabal-1.4.0.2.tar.gz
http://hackage.haskell.org/packages/archive/HTTP/3001.0.4/HTTP-3001.0.4.tar.gz
http://hackage.haskell.org/packages/archive/zlib/0.4.0.4/zlib-0.4.0.4.tar.gz

My guess here is that you have an older version of Cabal.  Could you
try ghc-pkg list Cabal?  In my eager GHC 6.6 days, I recall that
upgrading the Cabal library was not such a bad experience.  Maybe there
is an older but good-enough version of Cabal that will do the trick.

Sorry.  This was more troublesome than I anticipated.  I expect GHC 6.8
users to have a smoother experience at least :-)

Thanks,
