I'l start by giving you some system background info for reference -
Macbook Pro running 10.6.8
Processing 1.5.1 and 2.0a4 (error occurs with both)
I'm trying to do some projection mapping with Processing using the Keystone library from this site and I am encountering this error when running the CornerPin example -
The package "deadpixel" does not exist. You might be missing a library.
I believe I installed the package correctly, according to the instructions, but I may have missed something.
