Hello community of Seekers. I have here not so much a question as an alert about a problem I found when trying to use perlbrew on a cygwin system. Sorry for cross-posting, but after about a week there's been no action on this issue discussion I started at GitHub and anyway I thought it a good idea to get this information into Perlmonks database for later searchers.

In brief this is an issue with Gnu tar. This otherwise excellent workhorse for developers and users has a *nix-oriented "feature" wherein it takes a colon as in C: in a pathname on cygwin (yes, cygwin uses Windows paths interchangably with native cygwin paths rooted at /) ... tar takes it to mean an external tape drive or similar device, not a local path, and dies.

Those who developed tar foresaw the issue and provided the switch --force-local to alter tar's behavior, and the patch I submitted at GitHub uses this to work around the issue.

Hey, Merry Happy to all, thanks for reading.
