There's nothing relocatable about that - you simply break your perl
installation that way.

That's because you haven't relocated your perl, you just moved it
away. That jsut destroys your install, it doesn't relocate it.

I don't think cpan modules should support obviously broken installs - there
is a perfectly fine mechanism to find out which path to perl is the correct
one, and modules shouldn't need to second-guess that one in their testsuite.

You might want to look at the various windows perls which are relocatable,
to see how they do it.
