Rather than trying in your application, make a SSCCE. I got one working in 10min, and I don't usually export scalars, so don't have much experience with it.

pm1187349.pm

package pm1187349;
use warnings;
use strict;

use Exporter 'import';
our @EXPORT_OK = qw($someScalar someFunction);

our $someScalar = "Scalar Text";
sub someFunction {
    print "I am some function\n";
}
