----------------------------------------
I've installed on another SBC without a problem. Have I missed something?  Is there a
system build problem?  How to fix?
Thanks

[SOLVED]
I had missed the no Python.h in the output (it was late and I was tired - my excuse and...)
anyhow, tracked that down Python.h then apt-get install build-essential libssl-dev libffi-dev python-dev
and uninstall bf and install bf and then find out it's
/usr/local/bin/butterfly.server.py and not
/usr/bin/bf...

It's working.
