If you experience with 32bit containers you can also try to create Gentoo template whith with 64bits binary support. Try to download '''64bit''' stage3. For 64bit Gentoo template creation, search for nearest mirrors http://www.gentoo.org/main/en/mirrors.xml or directly from:

http://distfiles.gentoo.org/releases/amd64/autobuilds/current-stage3/ whith with 32bit binary '''multilib''' support, or

http://distfiles.gentoo.org/releases/amd64/autobuilds/current-stage3/hardened/ (stage3-amd64-hardened+nomultilib-20xxxxxx.tar.bz2) try the hardend profile whithout without multilib support (only 64bit binary support for gentoo template containers!!)

'''WARNING''': There is no warrantied that template should work, you can bugtack the errors. But I haven't confronted whith with problem.
