[Haskell-cafe] trouble building regex-base 0.91 on ghc 6.7

[Thomas Hartman]

I'm trying to build the latest regex base, which is required for the other 
regex packages under ghc 6.7

It complains that it can't find Data.Sequence, because it's in a hidden 
module containers. I added containers to the cabal depends as can be seen 
in the grep below.

And containers isn't hidden when I do ghc-pkg list.

What gives?

Still getting used to cabal...

thomas.
