Hello John,

I'm trying to install the new version of HDBC on my Mac (ghc version is 6.10.1), and get the following error:

# cabal upgrade --global

cabal: Error: some packages failed to install:
HDBC-2.0.0 failed during the building phase. The exception was:

I got the same error: Windows XP, GHC 6.10.1.

For some reason imported Control.Exception module appears to be 6.8.* version.
