Okay. Just so I know I understand what your saying...

If someone attempting to build B::Generate, was doing it on top of a copy of perl they had built themselves--which most unix people/perl hackers would be--then the "missing bits" would probably be "lying around" in appropriate places and would get picked up and used when building Generate.xs.

But because I was attempting to build on top of a binary distribution of perl, the objects and libs created by the Perl build process aren't there, hence the failure. And no amount of hacking, beyond rebuild perl myself and building B::Generate on top of that, is going to let me succeed.

Did I get it?
