Gview in vim should countinue to work but ...

Not in this instance, this is GaussianView - a (very expensive) commercial 
program for viewing chemistry "stuff". Actually, the main Gaussian product is
*hugely* expensive but has a 20 year licence term so is not bad for 
the cost

My suggestion is that you talk to the person at your work/academic 
institution who handles technical support and/or purchasing of this program
to ask them to contact the vendor. It may be that the vendor is not yet
up to date with Bullseye and still only supports Buster [in which case
it may be good to tell them it has < 1 year of full Debian support left.]
That would also explain why it is compiled against particular library
versions or whatever - and also why you need high performance graphics 
to work well for you.


Likewise, with luck, you've got someone who will help with some technical
support at your workplace/institution. Ask around?
