installing libapreq and MP1

[Marc Lambrichs]

I'm  trying to install a MP1 enabled apache in /usr/local/httpd_1.3.33 
and MP2 enabled apache in /usr/local/httpd_2.054. Now, when I try to 
install libapreq I get the following error:

mod_perl 1.x ( < 1.99) is required at Makefile.PL line 34.
BEGIN failed--compilation aborted at Makefile.PL line 36.
Actually, both are installed.
find /usr/local/lib/perl5 -type f -name "mod_perl*.pm" -print -exec grep 
"VERSION" \;
prints:

/usr/local/lib/perl5/site_perl/5.8.5/mach/mod_perl.pm
   $mod_perl::VERSION = "1.29";
   $class->UNIVERSAL::VERSION(shift);
/usr/local/lib/perl5/site_perl/5.8.5/mach/mod_perl_hooks.pm
/usr/local/lib/perl5/site_perl/5.8.5/mach/mod_perl2.pm
   our $VERSION = "1.999023";
   our $VERSION_TRIPLET;
   if ($VERSION =~ /(\d+)\.(\d\d\d)(\d+)/) {
       $VERSION_TRIPLET = "$v1.$v2.$v3";
       die "bad version: $VERSION";
   # $VERSION        : "1.099020"
   # int $VERSION    : 1.09902
   # $VERSION_TRIPLET: 1.99.20
   # $mod_perl2::VERSION for more granularity
   our $API_VERSION = 2;
$mod_perl::VERSION = $mod_perl2::VERSION;
How can I solve this?
Marc.
