Unfortunately for the "use lib" stuff, that's evaluated at compile
time before we can easily work things out cleanly - see
http://www.perlmonks.org/?node_id=285370 for more on this. There's
even code further down to work out directory locations. I've just
tried that and it doesn't help, because of the ordering. If we were
running in a normal perl script, we could use FindBin. But that
doesn't work for me in the embedded perl-inside-wml world. :-(
I've just committed an extra couple of directory levels of "../" now,
to get to a depth of 6. The deepest I can see in the webwml tree is 5
at the moment.
I'd love to hear better suggestions if anybody has any!
