There are sometimes problems like this one when you have old versions =20=

compiled or installed. Try this:

- First unregister all haskelldb packages:

$ ./unregister-all

- The make clean before configuring and building each package:

(For haskelldb and each driver-X:)

$ runghc Setup.hs clean
$ runghc Setup.hs configure
$ runghc Setup.hs build
$ runghc Setup.hs install
