Given the below you probably failed to uninstall Error.pm, or not
installing it in the first place doesn't matter because it's there

Right. I usually do

\$ perl -MYet::Another::Module

to convince myself that Yes::Another::Module really is not accessible
to the interpreter. And if I do that with Error on my OSX box I do

Now, I can't imagine that using Error::throw \$class <whatever> would
not die immediately if Error.pm is not installed. You can check that
quickly by mistyping the module name (like Errror::throw). So unless
there's some deep magic going on then using Error::throw instead of
just throw() is not an option I'm afraid.

I guess the solution needs to be adding the comma. I can't imagine why
this would break on non-Windows systems, but obviously some testing is
in order.
