installation error

I tried to install sage from source and also from PPA on Ubuntu 12.10. Both of them finish the installation without any problem, but when I run sage I get the following error:

k1@Think1:~$ sagemath

If you suspect this is an IPython bug, please report it at: https://github.com/ipython/ipython/is... or send an email to the mailing list at ipython-dev@scipy.org

You can print a more detailed traceback right now with "%tb", or use "%debug" to interactively debug it.

Extra-detailed tracebacks for bug-reporting purposes can be enabled via: c.Application.verbose_crash=True

But if I run it as root then it works fine. I have installed it all without root permission though. I thought it might be a permission problem and gave all the permissions for the files to the user k1, but still the problems exists.

So, I gained the permission to '/home/k1/.sage' and now it runs, but there are new errors:

[SageTerminalApp] Could not set security dir permissions to private.

[SageTerminalApp] Could not set pid dir permissions to private.

and I can't open the notebook().

the output of "ls -l /home/k1/ | grep .sage" is empty.

The output of "ls -l /home/k1/.sage" is :
