Gentoo install libgtk-x11-2.0.so.0

OS: Linux solar 3.1.6-gentoo #16 SMP Thu Jan 5 14:49:10 GMT 2012 x86_64 AMD Athlon(tm) 64 X2 Dual Core Processor 3800+ AuthenticAMD GNU/Linux

Problem:
I trying to run LDOCE5 and have this error:

Error while loading shared libraries: libgtk-x11-2.0.so.0. 

32bit applications need 32bit libraries, but I have 64bit system.

Solution: 

Many 32bit libraries on 64bit gentoo you can install with package app-emulation/emul-linux-x86-gtklibs. Also this package has needed libgtk-x11-2.0.so.0

LDOCE5 no sound solution.

You must had installed and configured 'alsa-oss'

Problem:
No sound in LDOCE5 application.

Solution:
Add 'aoss' to exec ldoce5 command.
Desktop link:
Edit desktop file ldoce5.desktop. Add 'aoss' in the command on Exec line
Exec=aoss '/<path_to_ldoce5_install_dir>/ldoce5//ldoce5'


Also you can create command in user '~/.bashrc' file. Add this line in your .bashrc file
alias ldoce5="aoss /<path_to_ldoce5_install_dir>/ldoce5/ldoce5"
And after reboot you can use 'ldoce5' command to execute application with fixed sound.

May be you have "aoss32" instead "aoss", it also working, trying.
