Ok, here's the code - it's not the cleanest code, but it seems to work for the relatively few modules I've tried it with. I call it 'pwhich' which functions sort of like the 'which' command on Linux: 
#!/usr/bin/perl -w
use strict;
my $perl_module;
BEGIN {
   my $ct_args = @ARGV;
   if ($ct_args != 1) {
      print "\nUsage: pwhich <perl module name>\n\n";
      print "Example: pwhich DBI\n\n";
      exit;
   }
   $perl_module = shift;
};
eval "use $perl_module";
die "Can't find Perl module $perl_module!\n" if $@;

my $inc_key = "$perl_module.pm";
$inc_key =~ s!::!/!g;
print "inc_key = $inc_key\n";
my $abs_filename = $INC{$inc_key};
print "\n";
print "Module:   $perl_module\n";
print "Location: $abs_filename\n";

open(IN,"<$abs_filename") || die "Can't open $abs_filename!";
my $version = "";
while (<IN>) {
   if (/\s*\$[\w:]*VERSION\s*=[ "']*([0-9_\.]+)/i) {
      $version = $1;
      last;
   }
}
close(IN);
print "Version:  $version\n\n";
