In your code there is a "the.patch". I'm not sure what that is, i don't have a patch for this problem.

:D Its the file generated by the ppport.h perl program, obviously :)

And I don't know how to compile a new perl which explicitly exports pad_swipe.

Me too :) I could go digging it up, but this is really a problem for the CPAN author to solve -- has to persuade p5p to add that symbol to the export list, or circumvent them by patching his code

Waiting is wise :)
