'I don't believe it is the case'-- trust me, it is the case. As to why it hasn't shown up, at a guess, the company in question doesn't use much (if any) external XS. I'm told that it wasn't left out intentionally. Of course the person who said that also didn't know the symbol in question<sigh> The perlapi.h seems fine, although I could diff it with the AS copy which is known to work. You said 'edit the appropriate makefile', could you be a little more explicit. I need all of the info I can get if I'm going to talk these guys through it (I can't do it hands on, I'm an outside contractor, so nix that idea). Thanks!
