New submission from Matt Morrison: I've been building Python 3 from source on Linux for a long time (at least since 3.2 days), and I honestly can't remember if this has happened before 3.6 or not, which is why I'm only tagging this 3.6.
Basically, when running 'make install' (after building either static or shared, I haven't been messing around with any other options except install prefix - $HOME) you'll start seeing messages like: ===== Listing '/home/mattdmo/lib/python3.6/site-packages/statsmodels/sandbox/regression'...

I usually don't pay much attention to them, but since I have nothing better to do I just stare idly at them and watch as all my third-party modules in 'site-packages' scroll by in alphabetical order very quickly. For the last few builds of 3.6, though, I've noticed that the modules get gone through twice. I have a pretty large number of modules (341, according to `ls | wc -l`), so it takes a while to go through them, and they're definitely being repeated. Unfortunately, I don't know a whole lot about Makefiles or the internals of the installation process, so I don't have the slightest idea of where to begin even looking for the bug. But, I bet you ladies and gentlemen do :) If it's necessary, I can rebuild and pipe all the output into a file for you to examine. Just let me know. ---------- components: Build, Extension Modules, Installation messages: 273824 nosy: MattDMo priority: normal severity: normal status: open title: during 'make install', pre-existing site-packages residents are recompiled.
