[Haskell-cafe] Installing grapefruit: "lexical error at character 'i'"

[Alexey Shmalko]

Hi,

Probably, the best solution in this case (and most similar cases) is
to send patch to upstream. I believe, grapefruit maintainers will be
glad to see it.

As far as I know, you can open a bug at
http://trac.haskell.org/grapefruit/. Mailing list is also a nice place
to try: http://projects.haskell.org/cgi-bin/mailman/listinfo/grapefruit

Regards,
Alexey
