MongoDB 3.2 on Slackware 14.0

Slackbuilds already have premade packages for MongoDB but the problem is, sometimes they are outdated. Some people might not want to upgrade their Slackware installation, and since I'm in such situation, here is my recipe

1. grab the aproppiate MongoDB from Slackbuilds to your version of Slackware. 
2. install it as usual with upgradepkg --install-new, but dont start it now
3. grab binaries from https://www.mongodb.com/download-center
4. unpack them
5. overwrite unpacked binaries in /usr/bin
6. and now you can start the server and restart Apache if needed
