Merge r1675441 from trunk:

      <dd>For some of the support scripts like <program>

      apxs</program> or <program>dbmmanage</program> (which are

      written in Perl) the Perl 5 interpreter is required (versions

      5.003 or newer are sufficient). If you have multiple Perl

      interpreters (for example, a systemwide install of Perl 4, and

      your own install of Perl 5), you are advised to use the

      <code>--with-perl</code> option (see below) to make sure the

      correct one is used by <program>configure</program>.

      If no Perl 5 interpreter is found by the

      5.003 or newer are sufficient).  If no Perl 5 interpreter is found by the

      <program>configure</program> script, you will not be able to use

      the affected support scripts. Of course, you will still be able to

      build and use Apache httpd.</dd>
