<title>Installation of Perl</title>

<para>Prepare Perl for compilation:</para>

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

<para>If you want more control over the way Perl sets itself up to be
built, you can run the interactive <command>Configure</command> script
instead and modify the way Perl is built. If you think you can live with the
(sensible) defaults Perl auto-detects, then just use the command listed
above.</para>

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

<itemizedlist>
<listitem><para><userinput>-Dpager="/bin/less -isR"</userinput>: This corrects
an error in the perldoc code with the invocation of the less
program.</para></listitem>
</itemizedlist>

<para>Compile the package:</para>

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

<para>This package has a test suite available which can perform a number of
checks to ensure it built correctly.  Should you choose to run it, you first
have to create a basic <filename>/etc/hosts</filename> file, 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>And install the package:</para>

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