# It looks like setuptools creates a .pth file in
# the default /usr/lib which causes the default site-packages
# to be inserted into sys.path before PYTHONPATH.
# This can cause issues such as having libsip loaded from
# the system instead of the one provided with Cura, which causes
# incompatibility issues with libArcus

PYTHONPATH = os.environ["PYTHONPATH"].split(os.pathsep) # Get the value, split it..
PYTHONPATH.reverse() # and reverse it, because we always insert at 1
for PATH in PYTHONPATH: # Now beginning with the last PATH
PATH_real = os.path.realpath(PATH) # Making the the path "real"
