As you can see from your own mail emul-linux-x86-compat does not install any 
libs into /usr/lib32. Therefore I still think that the description may be 
correct and that package may be unaware of multilib being enabled. 
Nonetheless it does solve the problem and that's good enough for me. :)

While this does explain that multilib is in fact enabled it tells me nothing 
about how it is supposed to work. Just above it [1] there is a section about 
the emul-linux-x86 packages which apparently explains that 
emul-linux-x86-compat should have been a dependency of overnet. But it does 
not state anything about multilib being required for those emul-linux-x86 
packages to work. And if multilib isn't required for it then I am uncertain 
about what good it actually does.
