Add gitfiletree:// Error

Ciao,

after load the GitFileTree on Pharo 5.0 ( I use the desktop Pharo image )

when in Monticello Browser  i add a new repository based on gitfiletree://  

after select a directory (on the local disk ) the system answer:

PrimitiveFailed: primitive #loadSymbol:module: in ExternalAddress class failed

The relative variable are:
loadSymbol: 'environ' module:  libc.dylib

The stack is:
