But shouldn't libstdc++-v3 install both 64 bit and 32 bit libraries then? It 
most certainly doesn't.

# equery files libstdc++-v3
[ Searching for packages matching libstdc++-v3... ]
* Contents of sys-libs/libstdc++-v3-3.3.6:
/etc
/etc/env.d
/etc/env.d/99libstdc++
/usr
/usr/lib64
/usr/lib64/libstdc++-v3
/usr/lib64/libstdc++-v3/libstdc++.so.5 -> libstdc++.so.5.0.7
/usr/lib64/libstdc++-v3/libstdc++.so.5.0.7

Also this leads me to believe that  the use flag is actually off. This may 
have no importance (because of the profile) but I am quite confused on how 
this is supposed to work.

# eix -s emul -S libstdc++ 
* app-emulation/emul-linux-x86-compat 
     Available versions:  1.0 1.0-r1
     Installed:           none
     Homepage:            http://www.gentoo.org/
     Description:         emul-linux-x86 version of lib-compat, with the 
addition of a 32bit libgcc_s and the libstdc++ versions provided by gcc 3.3 
and 3.4 for non-multilib systems.

The description leads me to believe that this is for non-multilib systems. But 
I want multilib. Am I missing anything here?

If anyone can direct me towards some proper documentation of how multilib is 
supposed to work I would appreciate that.

And as always thanks for your replies. :)
