A number of people have been having problems getting this to work on Tazz's GingerTazz rom. I did some experimenting and came up with the following:
The main problem is that the c2c script expects to be running in a Bash shell. The terminal-emulator app shell and the gscript shell were originally bash, but some other shell got substituted somewhere along the way. This explains why some boot and/or gscript scripts don't run at all and why they produce confusing error messages.
For users of Tazz's ROM, I included a step-by-step for running the c2c script manually here
in the GingerTazz thread.
Users of other ROMs who are having problems getting c2c (or other bash/gscript scripts) to work may want to take a look at the step-by-step instructions.
