[Fri May 19 17:59:26 2006] [error] Can't load Perl file:
/etc/httpd/conf.d/startup.pl for server celebration.eng.vmware.com:0, exiting...

the actual error is in CGI.pm around line 190:


  if (exists $ENV{MOD_PERL_API_VERSION} && $ENV{MOD_PERL_API_VERSION} == 2) {
    $MOD_PERL = 2;
    require Apache2::Response;
    require Apache2::RequestRec;
    require Apache2::RequestUtil;
    require Apache2::RequestIO;
    require APR::Pool;
 } else {
   $MOD_PERL = 1;
    require Apache;
  }

the problem is, redhat's mod_perl is 1.99, so $ENV{MOD_PERL_API_VERSION} is not
2 (this maybe should be fixed in mod_perl instead of here, i'm not sure). so
CGI.pm tries to load Apache.pm (which doesn't exist). if i comment out the if
statement and the rest of the else block (ie, if i don't check the api version
and just use the Apache2::* modules), everything works as expected.
