M6 REMAP ERROR

HiI'm trying to get my first three axis machine to work. I'm not able to understand why during auto tool
measurement (chapter 4.2.6) I receive this error message:
pycall(remap.change_prolog)failed
Seems to related to REMAP=M6 instance but I'm outing crazy because I don't find the way to solve the issue.

The problem maybe in the stdglue.py file copied from /usr/share/doc/linuxcnc/examples/sample-configs/sim/gmoccapy of the iso linuxcnc-2.7.14-wheezy.iso image
Please can someone help me?

Thanks for the attention

marco c.

Thanks for your reply
Yes all files in python folder are executable (now) but the problem persists
I'm using linuxcnc 2.7.15, there was an automatic update after first startup
marco

Hereafter
thanks

I'm really stupid...
sorry

something is changed but may be present some other stupid think I made...
linuxcnc starts but gmoccapy doesn't appare....

thanks

Sorry ...
Now seems to be all OK
thanks
