<P>
One has to ensure that <code>QWTDIR</code> and <code>LD_LIBRARY_PATH</code> have
been updated to include Qwt install path and libraries.
<P>
If the environment is not set up, one can add the libraries to the
.bashrc by adding <code>LD_LIBRARY_PATH</code>:
<PRE>
export QWTDIR=/usr/local/qwt-6.0.0/
export LD_LIBRARY_PATH=$QWTDIR/lib:$LD_LIBRARY_PATH
