21 market join on Raspberry Pi 3 gives error #23

When doing the setup on Raspberry Pi 3, I get the error that the platform is not supported. But I see Raspberry Pi in the list of supported platforms in the error.
The reason could be in the underlying hardware.

In the file /master/two1/commands/market.py, in line no. 173, the code is:

info = open("/proc/cpuinfo").read()

and in line no. 180, it does:

is_raspberry_pi = 'BCM27' in info

but, for my Raspberry Pi, the value is BCM2835, due to which I get this error.

Maybe only checking with BCM should be enough. Thoughts?
