Re: [Visualpython-users] VPython working on Mac OS 10.3.2

[Kelvin C. <kel...@uv...>]

Hi Joe;

Glad to hear that things are working.  Some Unix and fink-related
notes:

1)  To change your shell (back) to tcsh, type:

			   chsh (username)

    and then enter /bin/tcsh at the prompt.

2)  To put vpython in your path, you will need to have /sw/bin in your
    path, which means adding the (appropriate) line to your .cshrc or
    other shell-appropriate startup file.  This procedure is
    documented in the fink install instructions.

3)  X11 and xterm get environmental variables from the shell (ie X is
    a windowing system, not a shell).  

4)  I've amended the posted build instructions to include the
    directions for the bash shell.
