Found the following issues:
** install --user for hugs doesn't work at all

** install for hugs doesn't know the trick of checking in the library
   directory for other-modules while building an executable

** copyFile for hugs doesn't work on binaries?  I get an error about
   encodings during copy step when cross-installing GHC libraries with
   Hugs build.  This may mask other problems since its hard to test
   cross-installing.
