IMHO you should NAK such a patch as this is definitely an issue coming
from our 17.1 profile's new lib directory structure.
If you commit the suggested patch, all 32bit 17.1 profile installations
will suffer from the bug our 64bit 17.1 profile installations currently
suffer from.

We changed the following directories on 64bit arches with the 17.1
profile:

17.0:

# ls -ld /lib*
lrwxrwxrwx 1 root root    5 May 17 10:24 /lib -> lib64
drwxr-xr-x 1 root root 1174 May 17 10:26 /lib32
drwxr-xr-x 1 root root 5078 Jun 13 18:50 /lib64


17.1:

# ls -ld /lib*
drwxr-xr-x 1 root root 1382 May 13 22:54 /lib
drwxr-xr-x 1 root root 5340 Jun 18 10:23 /lib64


As you can see, "lib32" became "lib" and "lib" is no longer a symlink
pointing to "lib64".

My suggestion is to let the Gentoo package maintainers handle this in
the affected x2go package's ebuild files. We have a function called
"get_libdir" that can be used with sed to set the correct lib dir
name in the affected code.
