Steam says I'm missing the following libs, I'm hoping someone can help me get things in better shape:

xyz@abc:~$ STEAM_RUNTIME=0 steam
Running Steam on ubuntu 14.04 64-bit

I tried installing the following i386 packages: libpango-1.0-0:i386, libpangoft2-1.0-0:i386, and libgdk-pixbuf2.0-0:i386, and symlinking the .so files (from usr/lib/i386whatever../) into the ~/.local/share/Steam/ubuntu12_32/ folder, but wasn't able to find the right match for the gtk-x11 lib, and ultimately would up with a different, but still non-working situation. So I've back-tracked to this point, and have removed those i386 packages for now.

It's worth noting thatSteam runs if I don't use STEAM_RUNTIME=0. Also, Steam seemed to "recognize" the i386 version of the libpango & libpangoft2 libs after I symlinked them into place, during the course of my troubleshooting; when I would rerun STEAM_RUNTIME=0 steam, it wouldn't list those two items as missing anymore. Instead though, I had a bunch of gtk-related issues, something about overlay-scrollbar not available, as well as warnings that it can't find the murrine engine... a whole bunch of stuff that sounded like I'd gone too far down the wrong path.

Anyhow, any help sorting this out would be appreciated, and thanks!
