There is a /usr/bin/ghc Bourne shell script:
#!/bin/sh GHCBIN=3D"/usr/lib/ghc-5.02.2/ghc-5.02.2"; TOPDIROPT=3D"-B/usr/lib/ghc-5.02.2"; # Mini-driver for GHC exec $GHCBIN $TOPDIROPT ${1+"$@"}
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?
