(You get this message, because MakeMaker could not find "/System/Library/Perl/5.8.1/darwin-thread-multi-2level/CORE/perl.h")
This is the stock perl install from Panther, and I'm up to date. I did find the
perl.h file in /System/Library/Perl/darwin/CORE/perl.h,
The perl.h you found is from the older 5.6 Perl included with 10.1 & Jaguar. Since the older Perl is still there, I'm guessing that you upgraded to Panther, and didn't choose the "clean install" option. That's not a problem - just explaining why you found a copy of perl.h in a location other than the one where the current Perl expects it. ;-)
Have you updated your developer tools? If so, did you install the "BSD SDK" sub-package? That's the package that installs the Perl headers. It's optional but installed by default.
