FireFox, pgo-profile-run Error

I have tried a number of options to get this error to go away including adding the “pgo test” use flags

File "/usr/lib64/python2.7/BaseHTTPServer.py", line 108, in server_bind
SocketServer.TCPServer.server_bind(self)
File "/usr/lib64/python2.7/SocketServer.py", line 431, in server_bind
self.socket.bind(self.server_address)
File "/usr/lib64/python2.7/socket.py", line 228, in meth
return getattr(self._sock,name)(*args)

ALSO This taken from elog log file for firefox stated this

WARN: unpack
Sorry, but firefox-50.1.0 does not support the en_AU locale
ERROR: compile

Now if it will not build profile because of my LOCALE then what can I do?
Thanks AnyOne
