Hi all!
I do not know - it is an bug, or my mistake. I am trying to plot sum
of a few same functions:
This is my function:
B=10*sqrt( pi)/7;
b=pi/7;
c(f)=B*exp(-(b*f)^2);
plot(c(f),(f,-5,5));
in the output i see correct graphic.
Then i have define a function to calculate sum:
def specsum(x,Fd

I am trying to use the Python Imaging Library which I can only manage
to install in my OS X framework verison of python. So as a kludge I
am trying to run that system python from within Sage's python. But
when I do:
import os
os.system('/Library/Frameworks/Python.framework/Versions/Current/bin/

It did not work. I wrote a shell script SetMyPath that changes the
PATH, and i tested that from

Dear team,
in some Sage/Cython program i am also using some executables. More
precisely, it is a Gap sub-process that needs to run these
executables.
Now i wonder whether it is possible to change my PATH from within a
Sage session.
I know that i can get the PATH with
sage: os.environ['PATH']

This is related to http://trac.sagemath.org/sage_trac/ticket/3847
I have just put up a patch that fixes this issue.

a few days ago i was banging my head against the wall with the
tutorial after installing sage, then just now decided to search the
support group here.
i have the same sort of behavior as gary, with the jmol site working
fine, as well as the sagenb site:
http://groups.google.com/group/sage-support
Indeed, I believe that I have experienced the same.

Dear Mike,
Thanks a lot for the patch. Unfortunately, I am travelling until 23 Sept and
unable to hook up my laptop to the internet, so I can only test it when I
come back.
Cheers

thanks. That sounds pretty reasonable. I will give it a try.
