This is the same as bug 252483, which I can't reopen. The package dvdrip is masked for 64-bit-native systems for allegedly depending on multilib. In fact it doesn't. The line concerning media-video/dvdrip should be removed from file /usr/portage/profiles/arch/amd64/no-multilib/package.mask too. Reproducible: Always Steps to Reproduce: 1. Use a no-multilib profile 2. emerge dvdrip Actual Results: emerge fails complaining that the package relies on amd64 multilib. Expected Results: Compilation should go ahead. If you unmask the package and proceed with the installation, everything goes fine and the program works correctly.
thx for the report, I unmasked it on no-multilib
