[Chimera-users] [External] import error from module: Togl

I apologize in advance if this becomes too system-specific, as I believe
an automatic update of our server's python libraries may be to blame for
this error. However, my hope is that others may have run into the issue
as well and have already found a solution.
I have a python/chimera script that generates Chimera scenes with
various annotations assigned to residues in a protein structure. This
script worked without issue for several weeks. I returned from a week of
vacation and now the script fails with the following error:
ImportError: No module named Togl
line 73, in <module>
Togl appears to be a deprecated library, so my best guess is that it was
removed during some automatic update (possibly of PyOpenGL?) applied to
our servers. However, Chimera is distributed with its own python
executable and libraries, so I'm unsure how this type of change could
have affected it. I am using the nightly headless linux build of Chimera
from 05-13-2014. I have reinstalled chimera from the original .bin file,
and I have also installed the most recent nightly headless build.
Neither resolved the issue. I'm additionally confused because the
exception is raised by tkgui.py, which by naming convention seems like
it shouldn't even be called given that I am passing the "--nogui
--silent --script" parameters to chimera.
The specific call to chimera is this:
chimera --nogui --silent --script 'lib/PDBMapVisualize.py 1hho 1 maf
temp/61098856282.TEMP 1.000000 0.000000
Where lib/PDBMapVisualize.py is my script and everything following are
arguments to that script. Nothing about this call or the script it is
calling have changed between when chimera ran successfully and now.
Any help or advice in resolving this issue would be greatly appreciated.
