Hi,
There seems to be a packaging issue with the latest tagged commit:

$ pip install https://github.com/mogui/pyorient/archive/v1.4.5.zip                                                    Err 1 #269

    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):

    IOError: [Errno 2] No such file or directory: 'README.rst'

Command "python setup.py egg_info" failed with error code 1 in /var/folders/t5/42snzyyj0nn4s2fvhykwt2bw0000gn/T/pip-bFZ441-build

... while the version 1.4.3 installs without issue:

$ pip install https://github.com/mogui/pyorient/archive/v1.4.3.zip                                                    Err 1 #270
