- Download httrack ; for example the latest release, 
httrack-3.31.tar.gz ; in the /tmp directory

- Build it:

cd /tmp
tar xvfz httrack-3.31.tar.gz
cd httrack-3.31
./configure --prefix=$HOME && make && make install

That's all. No need to be r00t.

Then, you can add $HOME/bin in your PATH list, and possibly 
LD_LIBRARY_PATH:

export PATH=$PATH:$HOME/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$HOME/usr/lib

(you can put these lines in your ~/.profile file)

Then, launch httrack:
httrack
or launch webhttrack to get the GUI:
webhttrack
