Hello monks,

I've built an application which is designed to run both normally on Linux, or packaged up on Win32 with Cava Packer. Cava Packer comes with Cava::Pack, which I need to fake out, because as far as I can tell, there is no equivalent module for Linux.

I've worked around this with the following code:

BEGIN {
    package Cava::Pack;
    sub Resource { $Cava::Pack::dir.'/'.$_[0]; }
    sub SetResourcePath { $Cava::Pack::dir = $_[0]; }
    sub GetInfoProductVersion { "0.9.9.0"; }
}

This works fine in Linux, but in Windows I need to use the real Cava::Pack, and if I add a use Cava::Pack; line, I get function redefinition warnings (not to mention compilation fails on Linux because there is no Cava/Pack.pm in my @INC.

What I need to do is conditionally use the real Cava::Pack if it is available, or run my above code if it is not available. How do I go about that?
