I had ran into a few issues when I tried running Komodo on my desktop machine that is running an AMD64. The install went just fine, but when I tried to run Komodo it would fail while looking for libraries. In my particular case it was the libgtk-x11-2.0.so.0. When I did `ldd komodo-bin`, I realized that was not the only library that was missing. It ended up I needed to install more lib32 compat libraries. The fix to the issue was to emerge ‘app-emulation/emul-linux-x86-gtklibs’ which fixed all my problems and allowed me to run Komodo.
Here is a list of the emul libraries that I have installed on my system in case other people are having problems:
app-emulation/emul-linux-x86-baselibs
app-emulation/emul-linux-x86-compat
app-emulation/emul-linux-x86-glibc
app-emulation/emul-linux-x86-gtklibs
app-emulation/emul-linux-x86-java
app-emulation/emul-linux-x86-soundlibs
app-emulation/emul-linux-x86-xlibs
I’m not saying that you will need all of these. More than likely you will not need them all. This is just the list of the ones that I had installed when Komodo is working.
app-emulation/emul-linux-x86-gtklibs seems to make the trick.
