When I emerged thunderbird-bin, I was unable to start it because of a missing libstdc++.so.5. I checked that I had it and emerged libstdc++-v3 (the compatability version) and it worked. This library should be made a dependency of thunderbird-bin. Reproducible: Always Steps to Reproduce: 1.Emerge thunderbird-bin 2.Run thunderbrid-bin at command line. 3.Emerge libstdc++-v3 4.Run thunderbird-bin again. Actual Results: I was able to run thunderbird-bin after the emerge of libstdc++-v3.
Except that it already depends on virtual/libstdc++ on x86 and emul-linux-x86-compat on amd64.
