I can't replicate the problem. What are the symptoms? What is
PKG_CONFIG being passed as? If you unset it, dune uses "pkg-config",
which is fine for pkgsrc. But it seems like for it to be failing we
must be passing something wrong, and we shouldn't do that.

That was obviously wrong, yeah.

Please don't until we understand what's going on...
