[Haskell-cafe] HDBC-ODBC build/install problem.

[Bjorn Bringert]

This is probably a HaskellDB or hs-plugins problem. DBDirect uses hs- 
plugins to load driver modules, and I believe hs-plugins has  
undergone some changes to work with GHC 6.6.1, which DBDirect might  
not take into account. I don't use the DBDirect executable myself,  
since it tends to run into this sort of problems. Instead I write a  
small wrapper program around the DBDirect API that uses the driver  
I'm interested in at the moment.

If you want to try to fix it, see driver-dynamic/Database/HaskellDB/ 
DynConnect.hs. My guess is that the loadPackageFunction function  
there doesn't work with the current hs-plugins.
