+**7.** Setup the proper UNIX environment using the ''thisroot.csh'' script that comes with the ROOT installation.
+<code>
+setenv ROOTSYS ~/local/opt/root
+source $ROOTSYS/bin/thisroot.csh
+</code>
+:!: //**Note**//  \\
+Don't put a ''source /path/to/thisroot.csh'' statement in the home ''~/.chsrc'' file! It doesn't work with csh/tcsh!
+\\
+__**Missing fonts**__
+At ROOT startup, warnings about missing fonts appear:
+<code>
+linux% root
+Couldn't find font "-adobe-helvetica-medium-r-*-*-10-*-*-*-*-*-iso8859-1",
+trying "fixed". Please fix your system so helvetica can be found,
+this font typically is in the rpm (or pkg equivalent) package
+XFree86-[75,100]dpi-fonts or fonts-xorg-[75,100]dpi.
+...
+</code>
+Fixed by installing all ''xorg-x11-font*'' packages (12 MB). This is the same issue encountered with Cadence IC6.x!
+<code>
+linux# yum install xorg-x11-font*  (it doesn't work with sudo!)
+</code>
+\\
+__**PyROOT installation**__
+By default, PyROOT bindings ''ROOT.py'' and ''libPyROOT.so'' have not been created despite the usage of ''--enable-python''
+when running the ''configure'' script. Actually, neither Python header files (e.g. ''/usr/include/python2.x/Python.h'')
+nor libraries (e.g. ''/usr/lib/libpython2.x.so'') are included in a basic //Desktop// installation.
+In fact, ''python-libs'' and ''python-devel'' packages are missing.
+<code>
+linux% sudo yum install  python-libs  python-devel
+</code>
+\\
+Then re-run the ''configure/make/make install'' procedure again to install missing PyROOT components:
+<code>
+linux% ./configure --enable-python --with-python-incdir=/usr/include/python2.6 --with-python-libdir=/usr/lib
+...
+Checking for Python.h ... /usr/include/python2.6
+Checking for python2.6, libpython2.6, libpython, python, or Python ... /usr/lib
+...
+</code>
+At the end, ''$ROOTSYS/lib/ROOT.py'' and ''$ROOTSYS/lib/libPyROOT.so'' have been properly installed. To use ROOT within Python,
+the proper environment is correctly setup by sourcing the ''thisroot.chs'' script.
