Brian,

It points to something getting borked with perl. After all, Safari and curl 
both successfully fetch the URI, so it's not a networking problem. 

Date::Manip installed successfully, ergo ExtUtils::MakeMaker is now happy. 

The Extras/5.18 folder where DateTime and LWP live is in /System/Library/Perl 
not /Library/Perl.

I'm out of ideas why Yahoo!'s JSON server won't talk to your perl when it has 
no trouble with mine. The only thing left I can think of to try is to update 
LWP with 
  sudo cpan -i LWP

Regards,
John Ralls
