While attempting to create a virtual screen with a remote cluster run by
centOS, the error arose:

/loader/", line 409, in load_module
> ImportError: /usr/lib/x86_64-linux-gnu/ undefined symbol:
> xcb_poll_for_reply64

I am at debian9 amd64, where I have now noticed that VMD complains

opt/lib/vmd/vmd_LINUXAMD64: /usr/lib/x86_64-linux-gnu/ no
> version information available (required by /opt/lib/vmd/vmd_LINUXAMD64)

while functioning correctly.

Thanks for advice
