>From the GHC users guide:
"To compile a module which is to be part of a new package, use the
-package-name option:

-package-name foo

    This option is added to the command line when compiling a module
that is destined to be part of package foo. If this flag is omitted
then the default package Main is assumed."
It sounds like you forgot that flag when you compiled hsshellscript.
