Unable to start ledcontrol

[iamashwin99]

My installation from the master branch seems to have gone through (nothing to show otherwise) , however when I run the program I get the following error:

$ sudo ledcontrol --port 80 --led_count 200
Using default linear pixel mapping (200 LEDs)
Can't open device file
: No such device or address
Traceback (most recent call last):

RuntimeError: ws2811_init failed with code -9 (Failed to create mailbox device)

Does anyone one have any idea what might be going wrong

Please search for your error message in the issues at https://github.com/jgarff/rpi_ws281x or report this over there - it looks like it may take some effort to get this library to work on non-Raspbian operating systems.
