# can run sage as root but not as a regular (non-root) user

Dear Sage community.

I am not a Sage user but one of my user requested Sage installed on our Linux machine (CentOS 6.5). I've installed version 6.7 by simply unpacking a tar package with the binary inside.

Now I can start Sage as root. Typing ''./sage'' gives me "splash screen":

```
┌────────────────────────────────────────────────────────────────────┐
│ SageMath Version 6.7, Release Date: 2015-05-17 │
│ Type "notebook()" for the browser-based notebook interface. │
│ Type "help()" for help. │
└────────────────────────────────────────────────────────────────────┘
```

and command prompt after that.

If I do the same as a regular (non-root) user, I only get the "splash screen" and Sage hangs after that. No Sage command line. No response. I have to kill the process to get back to bash. When I do that I get the traceback information (attached).

I would appreciate any help with this issue.

Thanks, Eugene.
