Could you please say more.

I'm assuming that PYTHONPATH or xxx.pth would fix the problem and bailing at 
configure time just means you have to fix it pre configure/build, similar to 
setting things up by installing bison and various xxx-devel packages.

I was assuming we would add a configure option to bypass the bail/warn -- if 
necessary.  (Maybe add it anyway to cover our ass when it encounters a case 
we hadn't considered.)

I was assuming that destdir is only used to put stuff off to the side during 
packaging.  The will-it-work check should be concerned with the final 
destination so a configure time check based on prefix and pythondir seems 
right to me.

Is there another use case for destdir?
