Arches please mark the following versions as stable: app-mobilephone/gammu-1.22.1-r1 (keywords amd64,ppc,x86) app-mobilephone/wammu-0.29 (keywords amd64,x86) dev-python/python-gammu-0.28 (keywords amd64,x86)
Replace -r1 with -r2 ;). I've found out that the -r1 revision didn't installed libGammu.so and I've fixed that in the next revision.
ppc stable
amd64/x86 stable, all arches done.
