You need to install IPC::Run. You can only capture buffers under Win32
if you can use IPC::Run (and if you're not on Win98), and you can only
use IPC::Run if it's installed. Probably IPC::Cmd ought to depend on
IPC::Run if it's being installed under Win32, since it isn't useful
without it.
(As a hint, all of the above is very clear from the source of the
module. If a module's not doing what you expect, it's always worth at
least glancing at the source, to see if there's some obvious reason.)
