CPAN can't write makefiles after perl 5.8.1 reinstall on 10.3.4

[Brian Dimeler]

Hi, I was having trouble installing LWP on the version of Perl that came 
with our office iMac (running OS X 10.3.4) and therefore I reinstalled 
Perl as per the suggestion of CPAN, using the guide at 
http://developer.apple.com/internet/opensource/perl.html .  Since doing 
so, not only can't I install LWP, I can't install --anything-- with 
CPAN. Any time it gets to the "Writing makefile for whatever.." step I 
get a "-- NOT OK," followed by the predictable failure of the make and 
make install steps. Perl itself had installed fine (I used the the 
Mac-preferred directories for installation), and I had installed the 
XCode Developer Tools before it. As far as I know there's nothing 
unusual about my configuration, and I don't believe Perl had even been 
used before I attempted this stuff.  Somebody else has GOT to have 
encountered this problem before...
