Steffen from modules@perl.org responded to my email yesterday and made me a co-maintainer of String::Strip. I've applied the 64 bit bug fix to it, and pushed 1.02 to CPAN. Thanks for everyone who responded to my thread yesterday about requesting co-maintainer. This is how open source is supposed to work!
String::Strip has a problem on 64 bit environments, and a release has not been made in over 10 years. I have sent an email to modules@perl.org asking for COMAINT as the author has apparently not been responding to RT tickets.
