How can I get a list of all installed 32 Bit packages on a Gentoo Linux system?
eix tool comes to help:
eix -I --installed-with-use abi_x86_32
-Iselects only installed packages
--installed-with-useselects packages with certain USE flag

-I, but I included it just as useful option in general. You may also be interested in the option
-U, which selects packages which have abi_x86_32, but not necessary were installed with it, and in combination with
-I it gives yet another list.
If you don't have
eix on the system yet, just install it with
