Error setting environment variables by sourcing
I'm a beginner of unix and struggling with problems. One of them is to run the sage in any directory by typing 'sage'. I have failed even I tried this for 4 hours. Please help me.
I'm using OS X 10.9 but I don't want to use 'alias'. As a practice I want to change PATH to make it.
I have tried
1) adding /Users/jeong/work/Sage/sage-6.4.1/local/bin to /etc/path using 'vim /etc/paths' I added it to the path. And I closed terminal. After opening it again and typing 'sage'. I got error messages
Error: You must set the SAGE_ROOT environment variable or run this script from the SAGE_ROOT or SAGE_ROOT/local/bin/ directory. Error setting environment variables by sourcing '/usr/local/bin/sage-env'; possibly contact sage-devel (see http://groups.google.com/group/sage-d...).
Even I change the '/Users/jeong/work/Sage/sage-6.4.1/local/bin' to '/Users/jeong/work/Sage/sage-6.4.1', it doesn't work.
2) making a symbolic link to /usr/local/bin command: 'ln -s /Users/jeong/work/Sage/sage-6.4.1/local/bin /usr/local/bin'
error messages :

3) making .bash_profile or changing .profile in the home directory
don't work.
Please help me
