Hi Dean, unless you turn off the autodeps stuff you get the dependencies 
automatically generated by  perl.req or perldeps.pl (pick your poisen) can 
parse your scripts correctly. 

As an interesting excercise, take perl.req (lives in /usr/lib/rpm) and
run one of your scripts through it:

	perl.req yourscript.pl

And then there is a perl.prov for provides.   Finally you can do the same
thing with newer versions of rpm with perldeps.pl  you just have to throw
a --provides or --requires switch on the command line.
