tye, thanks for pointing me there. Unfortunately, IPC::Run is a catch-22. I'm doing this to automatically install new modules, and using IPC::Run means I need to install it first. I've used IPC::Open3 in the past, and found it annoyingly complex, and thought I hit a gold mine with this new open :-) Guess not.

Note that IPC::Open3's documentation, now that I'm looking at it again, explicitly says that "-|" doesn't work on Win32. That's unfortunate, but it shows more evidence that this is indeed the problem, and I need to work around it prior to further testing of my code.

Thanks!
