RT On Intel Mac? - Answer

A while ago I posted the query:
Is there a secret to being able to get all the required perl modules to
compile/install on an Intel Mac?

Attempting:
install Bundle::CPAN

…yields many instances of:
*** No rule to make target
/System/Library/Perl/5.8.6/darwin-thread-multi-2level/CORE/config.h', needed byMakefile’. Stop.

Anyone know whether there’s a solution for this problem (and what it is)?

Although I didn’t get an answer, I did get a question that sparked an
investigation that led me to discover what I’d done … or not done, in
this case.

The Perl config.h file (and many other headers) are installed via the
Xcode install (available for free via http://developer.apple.com/, signup
required). 'Though I had installed most of the developer stuff, I had
omitted installing the BSD SDK support … which (Murphy’s Law says) is
where the Perl development headers are contained.

Hope this helps someone else.
