Failures in running tests

[ArchaB]

Hi,

I am trying to port grin on Ubuntu 16.04 ppc64le VM.

The steps I followed were

git clone https://github.com/rkern/grin
pip install nose
cd grin/
nosetests

Build was successful, but 5 tests failed.

..............FF..FFF.

Am I missing something?

Any pointer would be helpful.

Thanks.
