ChimeraX on CentOS 7

[jameskizziah@…]

Hello,

While attempting to establish ChimeraX (using the most recent daily build)
on our CentOS 7 workstation, I have already downloaded and located the
necessary libraries as described in the Linux download notes.

Though this resolved the relevant error referenced in the notes, I am now
receiving the following error:

I was just coming to report the same issue! Seems to be a Linux-wide thing. For what it's worth, commenting out line 551 of ChimeraX_main.py seems to get things running with no obvious problems.

This bug has been fixed in the current daily build.
