quick helpful addition:

there are a couple ways to include whatever modules you install in your own space. the one i tend to use for situations like this is:

use qw(/path/to/your/custom/install);

use lib qw(/path/to/your/custom/install);
use XML::Parser;
[download]

... etc.

Update:

FoxtrotUniform caught that typo. Thanks, FU ;-)
