[I did the above from the command line interface. Read on to see why]
Also, I just tried to use the magma interface on my macbook. This is
a weird problem. I first started the notebook and typed
sage: magma('1+1')

TypeError: Unable to start magma
I realized that I didn't have the magma executable in my default
path. So, I made a symbolic link from /usr/local/bin/magma to where
the magma executable is. Tried again -- no dice. I stopped the
server and exited sage (I'm using the Sage.app), and started again --
still no change. Now here's the weird thing -- if I just start up
sage from the command line, and I type
sage: magma('1+1')
everything works ok. I just can't do it from the notebook. Since I
had installed 10.7 Lion the other day I thought that possibly sage
needed rebuilding (even though it had been running ok). I did a sage -
b . It recompiled a lot of things, but the behavior hasn't changed.
Any suggestions?
