We already have a minecraft ebuild in overlays. Maybe you can try that. If Minecraft binary itself doesn't support amd64 you can try running it with emul-linux-x86-java Closing as invalid since this is not an issue with a portage package.
It is not about ebuilds or minecraft being 32bit. The issue here is that it used to work and it is broken on jdk 1.7/icedtea-bin-7. without running emul-linux-x86-java

Confirmed, does not happen with icedtea-bin-6
(In reply to comment #4) > Confirmed, does not happen with icedtea-bin-6 And what about oracle-jdk-bin:1.7? emul-linux-x86-java is a separate package.

Then the only thing is to go upstream (minecraft) with that issue. There shouldn't be a 32bit lib in the library.path. Looks like there is an assumption made which no longer holds for java 7. IcedTea does properly identify itself as linux-amd64 here. As a workaround you can try adding the 64 bit .so to LD_LIBRARY_PATH or using the ebuilds in ::java-overlay.
