I inadvertently passed the file name of the package file as package name and it gave me back the whole file name. Right. .hi files track package dependencies. -package-name isn't a no-op on any platform with respect to dependencies, but it is a no-op with respect to dynamic linking on Unix. You should still use -package-name. As Simon said, the package handling is changing quite a bit for 6.4. In particular, .hi files no longer contain the contents of the -package-name flag when they were built. However, you still need to pass a flag when building a package, but now you say '-ignore-package P' to cause GHC to ignore any installed version of P when building modules that are contained in P. To ease migration, we made -package-name be a synonym for -ignore-package. So this particular error message should be a thing of the past. Furthermore, you can build a collection of modules once and then put them in two or more separate packages, or a package and a binary, without having to build them multiple times with different -package-name flags.

Hi Axel, No, I patched the hsshellscript library distribution to build using -package-name hsshellscript as you mentioned. I still got the error. (The documentation asserts that -package-name is a no-op on unices anyway. I wonder if that is really still true?) That's why I said that the error message was confusing: I had already rebuilt using -package-name and still got an error.
