"We" don't have this package because it can't work correctly on Cygwin
in certain circumstances (see below) and upstream didn't want to change
the way semaphores work to accomodate this situation.

That's most likely List::Util colliding with some other DLL or getting
intercepted by BLODA.

You'll either need to rebase all XS modules it installed manually or
install them from setup.exe before installing parallel.  Note that
parallel can't work correctly when your home is on a file system with
ustable inodes and thus can't refcount hardlinks.
