On macos it does not seem to work with engines implemented as executable scripts

[cristivlas]

I have an engine that consists of a Python script that implements the UCI protocol, and imports an extension written in C++.
The script is marked executable with chmod +x
Tried adding it to Banksia and it does not work (says engine does not implement any protocol).
My engine works fine with xboard and cutechess under macos and linux and with Arena 3.5.1 on Windows.
