Non ZMQ doesn't work

[rchiodo]

Not sure what the problem is, but if I go backwards to version 1002021048 everything works fine.

One of the changes on here is causing non ZMQ to break for me:

Jupyter never responds to the waitForIdle.

This commit causes the error:

Looking at the difference in how things are launched, with the newer change, the PATH environment variable is cased differently.

Here's a working kernelspec (from previous commit):

working.txt

Here's one that doesn't (generated with commit id: 7308db8)
bad.txt

Not sure if this is the root cause or not yet, but it's at least a difference.

Casing seems to be the root of the problem. Not sure how but that fixes it for me.
