Unpin (again) conda=4.6 - does not really work on base environment

This will not work for a base environment. Must undo this for now.

Personally I just use pip install --editable . to install bob.devtools but for conda I saw this issue today. What I have found that works is to install bob.devtools like this conda install bob.devtools=version=build_string.

What is really bothering now is the pin on conda-build, I think.

Can't we get rid of that soon?

I don't remember. I think we had to update our channel first to use a newer conda to index it. Updating conda there lead to extracting all packages and running out of disk space.
