FreeBSD updates (#2)

* FreeBSD update

1. run the build with gmake build on FreeBSD
2. Using env instead of direct interpreter call in head of python script - more flexible use of python scripts (there's no default symlink like python2 or python3 in FreeBSD)
3. removing full path before of 'curl' to be able to run it by the script for dependency downloads

* FreeBSD Update

Change script header using env instead of direct Bash shell call (full path of 'env' is '/usr/bin/env')

* Update README.md

* Fixed update to work on FreeBSD too

After applying the meta-package it is more widely usable
