Unfortunately, that's not happening.  Cabal is clearly generating the module; I can see it in dist/build/autogen.  But my copy is overriding the autogenerated one, even for cabal builds -- at least, that's what I'm seeing when I run the binary out of dist/build/<package>/<executable>.

I'm no Cabal expert, but the first thing I'd try is to leave your copy out of the list of included files in the Cabal file.

I'm not listing the included files, actually -- all I have is a "main-is:" setting, and ghc is pulling the rest in through automatic dependency detection. Actually, that suggests another strategy: if there's a way in the cabal file to configure ghc's search path, then I could make sure that the cabal-generated file is seen before mine. It's a little fragile, though, as it depends on the precise place that cabal puts the generated file. I'll look into that. Richard
