My understanding is that embedding paths into code like this is 
something that Shouldn't Be Done unless absolutely necessary. It also 
adds the complication of the build system having to edit the code. I may 
need to recalibrate my understanding.

The need to copy the code across several files because it can't be 
imported doesn't help either, but that is a minor point; there are 
larger duplicates. I am fine with this solution if people can agree on it.

I definitely need to recalibrate.

I was aware of this from chasing down the bug on my system. Didn't 
consider it relevant to !615 because the sys.path builder is part of the 
distribution code.
