typo in makefile? and command for OS X

[dfl]

I had some issues compiling for OS X.

Firstly, the makefile seems to have a typo in the path to include pd-lib-builder.

dfl ~/Downloads/pd-ffplay/src [main] $ make
Makefile:14: ../pd-lib-builder/Makefile.pdlibbuilder: No such file or directory
make: *** No rule to make target `../pd-lib-builder/Makefile.pdlibbuilder'.  Stop.

On the last line of the Makefile I changed "../pd-lib-builder" to "./pd-lib-builder" and now it compiles.

Also in order to remove the "cannot be opened because the developer cannot be verified" error that pops up when I instantiate the object in Pd, I had to run the following command:

sudo xattr -r -d com.apple.quarantinsudo xattr -r -d com.apple.quarantine ffplay~.pd_darwin
