It almost certainly is, tsocks uses LD_PRELOAD to mangle it's magic so
that stuff works. I believe chromium has severe issues with tsocks
because of how it does it's sandboxing, but I honestly don't know how
to get around that.

On a properly setup Gentoo amd64 system, /lib is a link to /lib64, so
the error you get is not a path error, the chromium binary really
cannot (or will not) deal with tsocks.so

I don't see anything wrong with the rest of your config. I honestly
think you are dealing with a chromium feature not a chromium bug.

Have you searched chromium-specific sites to see what others have to
say?
