Sorry, I was imprecise. What I'm suggesting is that you drop the
runtime PATH-foolery and instead put this in configure's environment:
PROVE=$perlpathdir/prove
Otherwise you're basically lying to configure about what you're going
to use, and that's always going to break eventually.

Hm, yeah, the IPC::Run test would need to deal with this as well.
A PROVE_PERL environment variable is one way. Or maybe simpler,
just skip the probe for IPC::Run if PROVE has been specified
externally; assume the user knows what he's doing in that case.
Are there any other gotchas in the build sequence?

Do we have/need any explicit references to the test version of "perl",
or is "prove" a sufficient API?
