Hey, Brian, setting PATH in .bashrc doesn't work in every situation. Leo and JJ just tried it, and .bashrc wasn't being sourced. Moving .bashrc to .local.bash does work since .local.bash is sourced by .bash_profile on development machines.

Also, JJ was wondering if you could change the location of the Pythons to somewhere outside of the home directory. For instance, ~/workspace.

Thanks, this was helpful. The python make scripts assume gcc-4.2 is located in /usr/bin which was not the case on my setup. Fixed via symlink, but PyPy had flooded my buffer so it was difficult to figure out where the error was coming from.

@wickman are you interested in moving this to a full repo? That way people (aka me) could easily send in updates to new versions, etc

New canonical location at wickman/python-bootstrap. Thanks @wickman !
