 I have been experimenting with building Hugs from a source tarball on
 a computer with no Haskell stuff preinstalled at all.

 I noticed that the build fails when running Setup configure for any
 package because Cabal cannot find Hugs executable.

 OTOH, if there is Hugs installed earlier (on the PATH), output from
 Setup configure shows that the previously installed Hugs is used, not
 one just built.

 This can be easily fixed if proper --with-hugs command line argument
 is provided to Setup. This affects two files: libraries/Makefile.in
 and libraries/tools/convert_libraries.

 Also, if any package installed has configure script invoking runhugs,
 this would fail too because in-place runhugs is not on the path. This
 is fixed by exporting proper PATH variable from the convert_libraries
 script before running Setup configure.

 Proposed patch is attached.
