I think it makes sense in the long term at least. So I will submit the bug
report and hopefully you can bring up the discussion on p5p.

Indeed. CCing debian-devel to see if we have other solutions to avoid the
pre-dependency.

Another solution is to make sure that the eval construct copes well with
XS modules linked for another perl (ie if they fail at dlopen()). I don't
see a reason why this couldn't be a run-time failure like another one...
That would be the general solution.
