Re: [Fieldtrip] FieldTrip 0.2.4 conflicts with OpenGL 2.2.3.0

      Thanks, Gregory.  I just pushed (to darcs & hackage) FieldTrip-0.2.7, which
works with and depends on OpenGL>=2.2.3.0.

After upgrading OpenGL, I tried to re-install FieldTrip 0.2.4 and
encountered these errors, from GHC 6.10.1 on Fedora 10 Linux:

Previously, I had installed FieldTrip 0.2.4 with earlier versions
of OpenGL.  I got some scary-looking warnings in the 'configure'
step:
Configure warns: Warning: This package indirectly depends on
    multiple versions of the same
package. This is highly likely to cause a compile failure.
package graphicsFormats-0.1 requires OpenGL-2.2.1.1
package GLUT-2.1.2.1 requires OpenGL-2.2.2.0
package FieldTrip-0.2.4 requires OpenGL-2.2.2.0
-- but I did have both those versions of OpenGL installed at the time,
and it did work.
Is my best move now to re-install OpenGL 2.2.1.1 and OpenGL 2.2.2.0,
keeping OpenGL 2.2.3.0, or had I better remove the newest version
of OpenGL and just keep the older two?
I hope I'm not answering my own question here, in my previous post,
 about the desirability
of moving FieldTrip away OpenGL -- however, I think people meant
something more than version problems by that ;-)
