I installed tenshi-0.3.2 on an amd64 by adding the keyword manually and it did compile and run without any problem. Reproducible: Always Steps to Reproduce: 1. 2. 3.
I can confirm that it runs fine (although I stumbled across bug #77137 when trying it :( ).
I can second that the ebuild and program works fine under amd64.
The newer tenshi-0.3.3 still runs fine on AMD64. Perhaps this bug should be reassigned to amd64@gentoo.org? I'd really like to see tenshi keyworded ~amd64. After all, over 4 months should be enough testing to make sure it works on AMD64.
committed in portage thanks for reporting
