Theoretically the following commands are sufficient to install PCSIM globally on your Linux box if you have the neccessary write permissions and all the required software packages are already properly installed:
wget 'http://downloads.sourceforge.net/pcsim/pypcsim-0.5.0.tar.gz' tar xvzf pypcsim-0.5.5.tar.gz cd pypcsim-0.5.5 python setup.py install python setup.py test
