<para>If you want full control over the way Perl is set up, you can run the
interactive <command>Configure</command> script and hand-pick the way this
package is built. If you think you can live with the (sensible)
defaults it auto-detects, then prepare Perl for compilation with:</para>

<screen><userinput>./configure.gnu --prefix=/usr -Dpager="/bin/less -isR"</userinput></screen>

<para>The meaning of the configure option:</para>

<para>Compile the package:</para>

<screen><userinput>make</userinput></screen>

<para>If you wish to run the test suite, you first have to create a basic
<filename>/etc/hosts</filename> file, which is needed by a couple of tests to
resolve the name <emphasis>localhost</emphasis>:</para>

<screen><userinput>echo "127.0.0.1 localhost $(hostname)" &gt; /etc/hosts</userinput></screen>

<para>Now run the tests, if you wish:</para>

<screen><userinput>make test</userinput></screen>

<para>Finally, install the package:</para>

<screen><userinput>make install</userinput></screen>
