Apache2::RequestRec missing?

I’m attempting to install/config a new installation of RT 3.6.0 and
have hit a roadblock. I went through the install of all the perl mods
and ‘make testdeps’ showed: “Everything was found.”

I config’d apache as instructed also but when I start apache and go to
the url I get:

[Thu Jun 29 16:47:30 2006] [notice] Apache/2.0.58 (Unix)
mod_perl/2.0.2 Perl/v5.8.5 configured – resuming normal operations
[Thu Jun 29 16:47:41 2006] [error] [client] Can’t locate
object method “content_type” via package “Apache2::RequestRec” at
/opt/pkg/rt-3.6.0/bin/webmux.pl line 109.\n

The important section of webmux.pl is:
103:sub handler {
104: ($r) = @_;
106: local $SIG{WARN};
107: local $SIG{DIE};
109: if ($r->content_type =~ m/^httpd\b.*\bdirectory/i) {
110: use File::Spec::Unix;
111: # Our DirectoryIndex is always index.html, regardless of
httpd settings
112: $r->filename( File::Spec::Unix->catfile( $r->filename,
‘index.html’ ) );
113: }
114:# elsif (defined( $r->content_type )) {
115: #$r->content_type !~ m!(^text/|\bxml\b)!i or return -1;
116:# }

The important section of httpd.conf is:
NameVirtualHost *:81
<VirtualHost *>
ServerName some.cool.tld
DocumentRoot /opt/pkg/rt-3.6.0/share/html
AddDefaultCharset UTF-8

PerlModule Apache::DBI
PerlRequire /opt/pkg/rt-3.6.0/bin/webmux.pl

<Location />
 SetHandler perl-script
 PerlHandler RT::Mason

Any ideas? I tried adding ‘PerlModule Apache2::RequestRec’ to the
httpd.conf but then I got blank pages.
