title: Apache2::Request (libapreq2-2.13) on centos 5.5
body: <p>I'm having a torrid time installing Apache2::Request on Centos 5.5.  My apache is the standard one that came with centos.
  I'm installing from libapreq2-2.13 and a lot of dependencies didn't already exist.  I so far had to do:</p>
  
  <p>yum install httpd-devel     # for apxs</p>
  
  <p>I then did:</p>
  
  <p>perl Makefile.PL --with-apache2-apxs=/usr/sbin/apxs
  make</p>
  
  <p>The make step then told me i needed: ExtUtils-XSBuilder and Parse-RecDescent, which i duly installed.</p>
  
  <p>running make again gave the compiler error:</p>
  
  <pre><code>/home/xx/installers/libapreq2-2.13/glue/perl/xsbuilder/apreq_xs_postperl.h:22:34: error: modperl_perl_unembed.h: No such file or directory
  /home/xx/installers/libapreq2-2.13/glue/perl/xsbuilder/apreq_xs_postperl.h:25:33: error: modperl_common_util.h: No such file or directory
   In file included from Apache2.xs:45:
  /home/xx/installers/libapreq2-2.13/glue/perl/xsbuilder/APR/Request/Apache2/APR__Request__Apache2.h:1:22: error: mod_perl.h: No such file or directory
  </code></pre>
  
  <p>Can anyone tell me which package i'm missing?
  Is there not a method of installing this common package that "just works" (tm).
  Many thanks</p>
