Unable to install 0.2.0.4 with ghc 6.12.3: Control.Parallel.Strategies does not export rseq

[DougBurke]

I haven't upgraded to the bright new world of the 7 series, so have

% ghc --version
The Glorious Glasgow Haskell Compilation System, version 6.12.3
% cabal --version
cabal-install version 0.8.2
using version 1.8.0.6 of the Cabal library 

which ends up causing me grief when I try to install monoids:

% cabal install monoids

How does the shinier and newer 'reducers' package treat you?

Unfortunately installing reducers would require me upgrading some of the packages that come with ghc 6.12.3 - such as containers - probably due to injudicious cabal updates I've done in the past. I've been waiting for the next HP release so I can blow away my current install and forget about all this madness. Or I should just finally get around to using use cabal-dev.

Ick. I probably can't downgrade the version # dependencies on containers. They added a couple of methods for me over the last year or two. Not sure which packages of mine used them though.

I'm just playing around here, so I would not spend too many cycles worrying about it!
