Looks like Device::SerialPort wasn't installed (errors look pretty straightforward). How did you go about installing it? CPAN? Did you build it yourself? If so, did you do a 'make install'?
Just wanted to thank you for your help. I figured out the problem. I orignally used CPAN to install it and must have got an error, as I just installed it from the .tar.gz file and it worked fine.
Thanks again.
