158 The test suite must be run separately from the build, either before or
159 after the package is built and installed. Do not run
160 <command>make install</command>, after running the test suite. To build
161 and install the package, you need to start with a fresh or clean source
162 tree. For the test, you also need a clean source code, so either start by
163 removing the source code directory and starting over, by uncompressing
164 the source tarball or by running <command>make clean</command>. Then
165 configure again, adding <quote>--with-pydebug</quote> to the
166 <command>configure</command> switches above, run <command>make</command>,
167 then <command>make test</command>. Remember that some tests fail, if not
168 run in an X terminal.
