Oh drat, you're right.  I goofed on that.  OK, so this would have been
fine if I hadn't broken my own scheme then, eh?  If cabal said just
1.0.2, it would just work?

That makes a lot of sense.

Strange, I get rather different results here:

$ grep-available -n -e -P 'libghc6-.*dev' -s Maintainer|sort | uniq -c
      6 Arjan Oosting <arjan@debian.org>
      1 Chris Lamb <chris@chris-lamb.co.uk>
      1 Debian QA Group <packages@qa.debian.org>
      3 Florian Ragwitz <rafl@debian.org>
      1 Florian Ragwitz <rafl@debianforum.de>
     12 Ian Lynagh (wibble) <igloo@debian.org>
      1 Isaac Jones <ijones@debian.org>
      2 Joachim Breitner <nomeata@debian.org>
     15 John Goerzen <jgoerzen@complete.org>
      5 Marco Túlio Gontijo e Silva <marcot@riseup.net>
      6 Víctor Pérez Pereira <vperez@debianvenezuela.org>

Which, at least for myself, I can vouch is more in line with reality ;-)

Completely agreed.
