I have downloaded a Linux 64 bit binary of http://factorcode.org and want to run it.

The first time I tried running it, it said libgtkglext-x11-1.0.so was missing. So I went to software.opensuse.org, and installed it from there. Now when I try to run factor, I get:

Code:
rahul@acb70333:~/Dev/factor> ./factor

Symbol: gtk_gl_init

    ]

    ]
How do I fix the problem?

(For what it's worth, this binary works just fine on my another machine that has Kubuntu 12.04.)
