Hi Samuel,
Thank you for this. One thing: I made a mistake in my comments on
ask.sagemath.org. Changing sys.path changes the Python path, not the path
for executables. One option is to use
import os; os.environ["PATH"] += ":/usr/local/bin"
Any better ways to do this? Your pointer on how to include this into
IPython config files works, as long as the lines are in quotes:
c.InteractiveShellApp.exec_lines = [
'import os; os.environ["PATH"] += ":/usr/local/bin" ']
