I'm running MacOSX. It has perl 5.8.1. MacOSX has perl installed by default.
I ran the the algebradebug.php test. The first stage text translation gives me:
No text output available
So I figure that perl isn't running correctly.
when I run whereis perl, I get /usr/bin/perl
when I run perl algebra2tex.pl x/2
Can't locate HTML/Entities.pm in @INC at AlgParser.pm line 11.
BEGIN failed--compilation aborted at AlgParser.pm line 11.
Suggestions? Is AlgParser.pm incompatible with OSX?
