Thank you.  It would seem that this shell script is very different
in RPM-versions of ghc than the standard tar distributions.  In
particular, the regular expression 'libdir=.*' (which was supplied
to me by the GHC team as a foolproof way of recognising import
directories) is completely absent.

Here is a small patch to try to use the TOPDIROPT variable if the
libdir test fails.  Can you let me know whether it works please?

Regards,
