[Boulder.pm] How do I catch "Can't locate <module>.pm" errors at runtime

[DeAndre Carroll]

The thing to remember here is that 'use' is a compile time directive. It 
is shorthand for the following:

BEGIN {
    require YourModule;
    YourModule->import(LIST);
}

You could wrap the require and import steps in an eval {} and exit 
gracefully given an error (found in $@).

Hope this helps.
