Setting the environment variables CPPFLAGS="-I/gnu/store/y8c62fyb2x4g4qnl54pmlmid1fn8k3mx-zlib-1.2.8/include" LDFLAGS="-L/gnu/store/y8c62fyb2x4g4qnl54pmlmid1fn8k3mx-zlib-1.2.8/lib"
before running configure makes it work. (I've also printed inc_dirs in setup.py without that - and zlib didn't appear) So I guess the general question is how does Python set up inc_dirs ? And is it normal that C_INCLUDE_PATH and LIBRARY_PATH doesn't contain zlib ? Apparently, since guix-master python2-minimal 2.7.12 doesn't contain it either - and that one works... So where would it get the other entries?
