You can't...
PWS is Windows stuff, and libswf is available only for Linux... You can abtain a source code and if you are really savvy you might be able to create a .DLL...
By the way libswf works great in Linux. Configuration for that is really easy...
Do this:
1. Get yourself a linux distribution
2. Install it
3. post commend here again
and I'll write how you can get flash library going on you *nix box.
