package. Perhaps you have a copy of that module on the search path
somewhere, or inside the alsa-seq package?
This would confirm how I understood the linker message. Then I guess
that compiling all packages at once in a single build dir with cabal was
the problem. The command line was like:
$ cabal install --builddir=/tmp/dist --with-ghc=ghc7.8.0.20140228 poll
alsa-seq pkg1 pkg2 pkg3 ...
After compiling the packages separately the problem has gone.
I think I know what the problem was: 'poll' uses HSC as preprocessor,
thus preprocessed files were stored in "dist". This way the preprocessed
source files were available to GHC when compiling 'alsa' and thus it was
compiled again, but not registered in the 'alsa' package.
