Your package depends explicitly on dev-lang/ruby:1.8. Versions in this slot are no longer supported upstream and this slot will be removed from Gentoo shortly. Please adapt your package to use a newer slot of ruby or mask it for removal if it is not compatible.
Please check http://caca.zoy.org/ticket/99
dev-lang/ruby:1.8 will be masked within a week. Since ruby support looks optional for you package please either fix the bindings or remove the ruby support before that time.
The ruby USE-Flag has been package.use.mask'd. Please remove the broken support from your ebuild and clean up the mask afterwards.

The flag is not important, we just tried to cover everything libcaca had to offer at the time. I'll try to port it to newer ruby w/ next bump, if not sooner.
