Maybe GHCi has a bug when it comes to DLL lookup. I had an application that worked fine when compiled with GHC, but failed with GHCi (libglew.dll not found)
I used procmon<http://technet.microsoft.com/en-us/sysinternals/bb896645.aspx> to monitor which files the GHC* processes searched, and it seemed that the compiled version looked for libglew32.dll, while GHCi was looking for libglew.dll Since this only happened with our own wrapper project, I thought we made a mistake, but maybe you could also use procmon to figure out what GHCi is doing, it might be a bug.
