[mp2] Install error with Makefile.PL - uninitialized value at TestRun.pm

1. Problem Description:

  Installing mod_perl2, latest version(2.0.7), on hp-ux machine(B.11.31). 
  The "perl Makefile.PL" command returns the following error:

    % perl Makefile.PL MP_AP_PREFIX=/opt/hpws22/apache
    Reading Makefile.PL args from @ARGV
       MP_AP_PREFIX = /opt/hpws22/apache
    no conflicting prior mod_perl version found - good.
    Configuring Apache/2.2.*/ mod_perl/2.0.7 Perl/v5.8.8
    Checking if your kit is complete...
    Looks good
    ERROR from evaluation of /opt/mod_perl-2.0.7/Apache-Reload/Makefile.PL: Use of 
    uninitialized value in substitution (s///) at Apache-Test/lib/Apache/TestRun.pm 
    line 1100.

  A few other details:

    % httpd -v
    Server version: Apache/2.2.8  HP-UX_Apache-based_Web_Server (Unix)
    Server built:   May  7 2010 12:11:23

    % perl -v
    This is perl, v5.8.8 built for IA64.ARCHREV_0-thread-multi

    There is no apr-config or apu-config on my machine, but there is an
    apr-1-config and apu-1-config, so I created symlinks to both of those.

    There is a previously existing mod_perl installation (1.99), but it
    is in an obscure directory that is not in @INC.

  I have searched the mail archives and internets for anything related to
  this problem, but could not find anything useful. I am neither a Perl 
  nor sysadmin guru, and I don't understand enough of what the TestRun.pm 
  program is doing to figure out what might be wrong. 
  Any suggestions would be helpful.

  Thanks!
