Should the following work, or am I doing something wrong?
[mike@Vector ~]$ export MIKES_DIR=/home/mike/
[mike@Vector ~]$ /usr/local/sage-4.5.2/sage
----------------------------------------------------------------------

----------------------------------------------------------------------
sage: os.system('echo $MIKES_DIR')
/home/mike/
0
sage: os.path.isdir('/home/mike/')
True
sage: os.path.isdir('$MIKES_DIR')
False
I ask this because isdir() appears to be used in one of the scripts for building ATLAS to test whether you're trying to use system-wide atlas libraries, and I'm having trouble getting that to work.
