I know of no Perl solution, but in general you can (ab)use strace on most Unix systems, DTrace on Solaris, FreeBSD and MacOS X and FileMon on Windows.

There's a DTrace patch for perl floating around somewhere (you'll find a link to it in the p5p archives) that enables dtracing perl code (and not just the perl interpreter), I don't know if that's needed for the dtrace approach.
