[rt-users] RT On Intel Mac?

[rt-users-list at derman.com]

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 by `Makefile'.  Stop.

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