SOLVED. See at bottom.
Just upgraded to OSX Lion and trying to get my Perl install running again:
sudo /usr/bin/perl -MCPAN -e 'install "MODULENAME"'
with any value of MODULENAME that I tried (e.g. JSON) produces:
...
Checking if your kit is complete...
Looks good
Writing Makefile for JSON
make: *** No rule to make target `/System/Library/Perl/5.12/darwin-thread-multi-2level/CORE/config.h', needed by `Makefile'. Stop.
MAKAMAKA/JSON-2.53.tar.gz
/Developer/usr/bin/make -- NOT OK
I can't find anything resembling config.h anywhere, the directory exists though ...
Not even this works:
/usr/bin/cpan CPAN
SOLVED: Download and install latest version of XCode from AppStore. Note that just downloading XCode from AppStore does not install it (why, Apple, oh why?) but only dumps an installer into /Applications. Run the installer, which will fix this issue.

回答2:
I still had this problem after installing Xcode, because Xcode didn't automatically install the "Command Line Tools for Xcode" package. This is available from Xcode | Preferences | Downloads | Components and click 'Install' next to 'Command Line Tools'.
Now that this is a separate package, it's also possible to solve this problem without installing all of Xcode (ie. you can just install this package :-)
