Perl: Can't exec "make": No such file or directory

I'm trying to install Perl modules using the Mac Terminal with cpan and keep getting the message "Can't exec "make": No such file or directory" e.g.:

CPAN.pm: Going to build I/IN/INGY/YAML-0.90.tar.gz

Checking if your kit is complete...

Looks good

Writing Makefile for YAML

Can't exec "make": No such file or directory at /System/Library/Perl/5.12/CPAN/Distribution.pm line 2026.

INGY/YAML-0.90.tar.gz

make -- NOT OK

Running make test

Can't test without successful make

Running make install

Make had returned bad status, install seems impossible

Failed during this command:

INGY/YAML-0.90.tar.gz : make NO

I looked at this topic (https://discussions.apple.com/thread/2787550), installed Xcode, even su'd to root, still getting the same.

How can I get make installed?

thanks,

Scott
