r3 uses the older pingpatch when installing. r2 correctly included pingpatch2 which includes a neccessary bug fix. Reproducible: Always Steps to Reproduce: 1. 2. 3.
Fixed in CVS, but I am waiting to mark this ebuild for amd64 until I can get an updated alsa/libsdl from icculus on amd64. I would suggest staying with -r2 for now, as the ebuild suggest, since there's no difference betwen -r2 and -r3 on amd64.
