Greetings. Actually the problem is not even in the python3.5 installation itself, it was managed to be trivially assembled from source, but the fact that the pip module is missing after the installation, and through python3.5 get-pip.py, there is no reason to say that:
zipimport.ZipImportError: can't decompress data; zlib not available
My question is why pip is missing and how to put it. Thank!
