If the Markdown module is installed via CPAN rather than apt then
the module is actually Text::Markdown.

I had to edit the source to change this on my old server. I have filed
a [bug](http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=387687) against
the Debian markdown, which I guess you can consider a blocking bug of this.

I tried to come up with the magical invocation to allow either location 
to be used by ikiwiki, but I couldn't do it.

Ok, the markdown in CPAN must be an entirely different version then if it
doesn't has a Markdown::Markdown. Interesting, I'll have a look at it.

I think what I've committed now will work in all cases. Well, unless there
are even more forks of markdown out there (the CPAN module is a fork
apparently...)
