If the Debian 5 system is a server, I would remote mount my home
directory on my workstation with the hardware graphics driver, and run
chimera locally. Or you might be able to copy libGL.so from your
workstation to a directory in your home directory on the server and set
the LD_LIBRARY_PATH environment variable to that directory.
If the Debian 5 system is supposed to be a workstation, I would be very
tempted to reboot it with a Ubuntu Live CD and when done, reboot it back
to Debian 5, or maybe the administrators would be willing to make it a
dual-boot system. Your idea, of compiling a software-only version of
Mesa, should work if you set the LD_LIBRARY_PATH environment variable
In the LD_LIBRARY_PATH cases above you would need to start chimera from
the command line after setting up the environment or start chimera after
editing the CHIMERA/bin/chimera shell script.
Hope this helps,
