Hello fellow brothers, forgive me for I am novice.

I have only just started to learn Perl. I wanted to write a small app to read data from a serial device attached to my Mac.

So I wrote this: 

#!/usr/bin/perl
use warnings;
use diagnostics;
use strict;
#use 5.010; Only v5.8.8 on a Mac.

use lib '/opt/local/lib/perl5/site_perl/5.8.8/darwin-2level';
use Device::SerialPort qw( :PARAM :STAT 0.07 );

[download]
When I run this app I get this error: 
Can't load '/opt/local/lib/perl5/site_perl/5.8.8/darwin-2level/auto/De
+vice/SerialPort/SerialPort.bundle' for module Device::SerialPort: dlo
+pen(/opt/local/lib/perl5/site_perl/5.8.8/darwin-2level/auto/Device/Se

The key part of the message seems to be "Symbol not found: _PL_stack_base"

I have reinstalled Device::SerialPort from CPAN. That appeared to work.

I downloaded the package directly from CPAN and tried to re-make the module, using something like (I cant seem to find the exact instructions I used): perl Makefile.PL make make test sudo make install

As far as I can tell I have only one copy of SerialPort.pm installed.

I am running this on a Apple Mac using OS X 10.5.8, with a Core Duo CPU, i.e. 32bit. Perl is v5.8.8.

I did read somewhere that SerialPort.pm was Linux only. Is that true?

Any ideas?

TIA

Mark
