STEP 1) Get the source tar, check it and upack it
$ cd ~/
$ mkdir tor
$ cd tor
$ torsocks wget https://www.torproject.org/dist/tor-0.2.8.10.tar.gz
$ torsocks wget https://www.torproject.org/dist/tor-0.2.8.10.tar.gz.asc
$ torsocks wget https://www.torproject.org/dist/tor-0.2.9.6-rc.tar.gz
$ torsocks wget https://www.torproject.org/dist/tor-0.2.9.6-rc.tar.gz.asc

https://www.torproject.org/dist/tor-0.2.8.10.tar.gz
https://www.torproject.org/dist/tor-0.2.9.6-rc.tar.gz

$ gpg --verify tor-0.2.9.6-rc.tar.gz.asc tor-0.2.9.6-rc.tar.gz

If the signatures are good continue or check the sha256sum:

$ sha256sum tor-0.2.8.10.tar.gz
$ sha256sum tor-0.2.9.6-rc.tar.gz

If this matches then unpack the files:

$ tar -xvf tor-0.2.8.10.tar.gz
$ tar -xvf tor-0.2.9.6-rc.tar.gz

$ mv tor-0.2.8.10 tor_stable
$ mv tor-0.2.9.6-rc tor_alpha

$ cd tor_stable

Step 2) configure , make, link

$ ./configure
$ make
$ mkdir ~/bin
 export PATH=$PATH:/homeUSER/bin
$ cd ~/bin
$ ln -s ~/tor/tor_stable/src/or/tor tor_stable
!
New versions of tor >0.3.5.x build and link the binary in ~/tor/src/app/ as ~/tor/src/app/tor

$ ln -s ~/tor/tor_stable/src/app/tor tor_stable

$ cd ~/tor/src/config

$ su
# mkdir /usr/local/etc/tor
# mkdir /usr/local/share/tor
# cp torr.sample /usr/local/etc/tor/torrc
# cp geoip /usr/local/share/geoip
# cp geoip6 /usr/local/share/geoip6
# cd /usr/local/etc/tor
# tor_stable &
# torsocks wget https://raw.githubusercontent.com/endwall2/endware/master/endtorrc
# mv endtorrc torrc-defaults
# nano torrc-defaults

modify to your liking

# fg 1
# ^C (Ctrl + C)
# exit
$ cd ~/tor/tor_alpha

STEP 3) repeat configure, make, link

$ ./configure
$ make
$ cd ~/bin
$ ln -s ~/tor/tor_alpha/src/or/tor tor_alpha
$ cd ~
$ tor_alpha &
$ fg 1
$ ^C (Ctrl + C)
