Fix #140

[ngeiswei]

moses consistently fails on circleci but consistently passes on my systems. Can anybody else test that?

[vsbogd]

@ngeiswei , I have tried it in docker, as far as I see in moses cmake uses python 2.7 and nosetests with python 3. This is the reason why test fails.

So, the policy question becomes: do we merge anyway because we know "it works"? Or do we wait for a moses fix? (Since moses-python works with the old location, the fix for moses-python is to tell moses about the new location)

[vsbogd]

I see that I was not precise in my conclusion. Actually I am not sure that moses finds python2. What I saw is that test fails because it uses python3-nosetest and test itself is written using python2 syntax. I believe it is consequence of turning python unit tests on in opencog-deps. So may be solution is port python test to python3.

[linas]

@vsbogd yes, everything needs to move to python3. But that does not explain why circleci pases with the old cogutils path. For that, I am attempting this: opencog/moses#77

[linas]

Ohh.. that's interesting .. so, circleci passed here opencog/moses#74 but now it fails .. so indeed, @vsbogd, it seems that my explanation doesn't explain it; I suppose you're right..

[ngeiswei]

Thanks guys, I'm merging since it's clear the problem doesn't come from that PR.

I'm fixing the moses nosetests thing now. opencog/moses#78
