Update:
No help or infos received...
I could install pip with
opkg install python-pip
But after I cant install e.g. the twilio packages with
-opkg update
-opkg install twilio
Midnight commander (mc) is in any repository, I found no way to install it. Not nice but I can live with it...
In my mind, the Rev2 is not to recommend. I can't understand why they changed from Linino (worked fine) to OpenWRT.
Are there other opinions?
