[Chimera-users] running chimera 1.8 needs root privilege

I've been using Chimera 1.5.3 under Linux (Ubuntu 12.04, 64-bit) without 
problems; that version I had installedas root, andis owned by root.  
Just now I updated to version 1.8, which, initially, I also installed as 
root.  But trying to run it (as non-root) gave me fairly opaque error 
messages(copied below). On a hunch that it was a matter of privilege, I 
tried running with `sudo` -- which works fine.

Since it was not obvious where the problem lay, I cleaned out the 
installation, and installed anew as a normal user (me).  Accordingly, 
the whole installation directory tree is owned by me.  But still I 
cannot run it (same errors) as me, but only with `sudo`. Same user, same 
start directory, apparently the same Python (2.7) as works with v. 1.5.3.

I'm totally flummoxed!  Can't imagine where the privilege hang-up is.  
Any hints where I should look?
