Maybe you have an old (or broken) installation of DateTime? At least DateTime 0.70 has these two lines:

use constant INFINITY     => ( 9**9**9 );
use constant NEG_INFINITY => -1 * ( 9**9**9 );

Also, why are you testing the Perl module/program through "swish" instead of trying to eliminate the irrelevant parts? I would start with perl -MDateTime::Infinity -e1 resp. perl -MDateTime -e1 and slowly work my way up the chain until things fail.
