As mentioned in the documentation, add only one library at a time. If it
complained about "libstdc++.so.6" then add this one and see what happens.
Do not not add "libc.so.6" unless you have a reason to do so.

Try removing libc.so.6 from gex/ and see what happens (but keep
libstc++.so.6). I know it is counter intuitive.

Release 2.0.1 was built in 2011 and it is possible that I has running
CentOS 5 back then. My i686 build machine is a recent Ubuntu release.

I was including the libc version  by hand just for reference and I forgot
to do it this time; this should not be an issue.

Try removing libc.so.6 from gex/ and let me know what it happens. If it
still does not work we will need to perform a build on your machine. Please
post you reply on gradsusr in order to provide a searcheable reference for
this particular issue.
