After the addon installation on my CCU all files seem to be there but python was not in the PATH. It seems that the binary directory BIN_DIR=/usr/local/bin was missing so the setup/init scripts failed.
I fixed that by uninstall the addon, create the folder manually and install the addon again. Not it's working properly.
Thanks for reporting this issue. I just pushed a fix to the git. The new build should be ready in some minutes. The directory /usr/local/bin must have been created by another addon on my CCU before.
