I don't often use constants, but it seems it is as simple as:
## Begin FooConstant.pm
package FooConstant;
require Exporter;
@ISA = qw/ Exporter /;
@EXPORT = qw/FOO/;
use constant { FOO => 'bar' };
1;
## End FooConstant.pm
Then call the module with:
## Begin FooNeeder.pl
use FooConstant;
my $out = 'voila: ' . FOO;
print $out;
