[Solve] [AUR] sage-mathematics-bin permissions issue

Hi there,

I have one interesting issue. Seems, that when I run sage as a user, it can not access some files in the ~/.sage directory.
Therefore, I wanted to ls -l them. Here it is what I get:

12:33:48 | [ignas@ArchLap /home/ignas]
$ ls -l .sage/ipython/
ls: cannot access .sage/ipython/ipythonrc-tutorial: Permission denied
ls: cannot access .sage/ipython/ipy_profile_sh.py: Permission denied
ls: cannot access .sage/ipython/ipythonrc-pysh: Permission denied
ls: cannot access .sage/ipython/ipythonrc-scipy: Permission denied
ls: cannot access .sage/ipython/ipy_user_conf.py: Permission denied
ls: cannot access .sage/ipython/ipythonrc-physics: Permission denied
ls: cannot access .sage/ipython/ipythonrc-numeric: Permission denied
ls: cannot access .sage/ipython/ipythonrc: Permission denied
ls: cannot access .sage/ipython/ipythonrc-math: Permission denied
ls: cannot access .sage/ipython/ipy_user_conf.pyc: Permission denied

Can anybody explain why I can ls -l only with sudo? I mean, that I certainly own the files, but I can not access. What is happening here?

I believe, that this causes sage not to run when launched as a normal user. However, I am able to run it using sudo or root account.

Sorry guys... was thinking only about ownership and not the read/write rights...

I had to

sudo chmod 764 -R ~/.sage

And everything seems to be fine.
