Dear Adam, I do not have a Mac computer to reproduce the error, so what I'm going to suggest now is a bit of a shot in the dark.
A possible workaround could be: 1. Download file `virtualenv.py 2. Comment out line 339 in `install.py` (the one that reads `download(VIRTUALENV_...)` 3. Run the installation procedure again. -- You received this message because you are subscribed to the Google Groups "gc3pie" group.
