Just out of curiosity, wouldn't it be better to test with exists()?

I did a quick test using env.pl, which confirms that for me as well, the 
PATH_INFO variable exists only if there actually is something in the url.
That is:

  http://foo/bar.pl  -> no PATH_INFO exists in %ENV
  http://foo/bar.pl/ -> PATH_INFO = /

This holds both under mod_perl (with ModPerl::Registry) and under mod_cgi. My 
Apache is 2.0.52.

As an aside, I have distant memories of IIS/5.0 not being able to do path_info 
at all, at least not without certain arcane rituals too gross to detail here.

#!/usr/bin/perl
# env.pl
print "Content-type: text/plain\n\n";
print map { "$_\t=$ENV{$_}\n" } sort keys %ENV;
# end
