And it works! :D
For someone that encounters this problem in the future, just pass
os.environ in the "env" argument of spawnProcess, it'll "clone" the
current environment and make liquidsoap run!
Like this:
import os
[...]
reactor.spawnProcess(pp, "/usr/bin/liquidsoap",
["liquidsoap","file.liq"], env=os.environ)
