Public bug reported:

I'm using Ubuntu 14.10 on x64 with the latest updates.

The Factor language dynamically loads ``libGL.so`` for its graphical
environment. On machines with a Radeon card and the ``fglrx-updates``
package, the preferred ``libGL.so`` path is ``/usr/lib/fglrx/libGL.so``.

However, if ``libgl1-mesa-dev`` is installed, there's another
``libGL.so`` in ``/usr/lib/x86_64-linux-gnu/libGL.so``.

Now, I would like to remove `libgl1-mesa-dev`, except that it is
required for `libgtkglext1-dev` which contains the function
`gtk_gl_init()`, which is required for the graphical environment for
Factor.


The crux of the issue is that ``/usr/lib/x86_64-linux-gnu`` has higher priority 
than ``/usr/lib/fglrx``, so programs that load ``libGL.so`` find the mesa 
version first:

```
erg@erglinux:~$ ldconfig -v | grep "^/"
/sbin/ldconfig.real: Path `/lib/x86_64-linux-gnu' given more than once
/sbin/ldconfig.real: Path `/usr/lib/x86_64-linux-gnu' given more than once
/sbin/ldconfig.real: /lib/x86_64-linux-gnu/ld-2.19.so is the dynamic linker, 
ignoring

/usr/lib/x86_64-linux-gnu/libfakeroot:
/usr/local/lib:
/lib/x86_64-linux-gnu:
/usr/lib/x86_64-linux-gnu:
/sbin/ldconfig.real: /lib32/ld-2.19.so is the dynamic linker, ignoring

/usr/lib/x86_64-linux-gnu/mesa-egl:
/usr/lib/fglrx:
/usr/lib32/fglrx:
/usr/lib/x86_64-linux-gnu/mir/client8driver/mesa:
/lib32:
/usr/lib32:
/lib:
/usr/lib:
```


Would there be anything wrong with moving the ``/usr/lib/fglrx`` entries above 
``/lib/x86_64-linux-gnu:``?

This appears to be an issue with nvidia's binary drivers as well, since
``/usr/lib/nvidia`` gets searched after ``/usr/x86_64-linux-gnu``.

Finally, if ``libgl1-mesa-dev`` wasn't required for
``libgtkglext1-dev``, that would also solve my problem because I
wouldn't have the mesa drivers installed at all.

Thanks,
Doug
