Thanks, for your report. It was my fault. I should not have modified
utils/hsc2hs/Main.hs as described in the following links.
A fix is to replace your file <prefix>/lib/ghc-6.8.2/hsc2hs-bin with a
new one that you can download from:
a ppc version from:
<prefix> above is /usr/local (or the one you've configured with)
Does someone have a cute command to easily update this file in a binary
distribution (without unpacking and repacking), so that Ian can replaced
my binary-dists (replacing hsc2hs-bin manually is a bit of a pain).
