SSLLookup error

[JohnDi]

I installed Apache::SSLLookup using cpanm today. The constructor and "is https" seem to work OK:

my $r = Apache::SSLLookup->new(shift);
my $is_ssl_request = $r->is_https;

But the lookup_var function

my $dn = $r->lookup_var('SSL_CLIENT_S_DN');

produces this error in the Apache logs:

Can't locate auto/Apache/SSLLookup/lookup_var.al in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 . /etc/httpd) at <my location>/AuthorizeSSL.pm 

Has the installation gone wrong somewhere? A Google search for "lookup_var.al" returns nearly nothing.

Any/All help appreciated

Thanks
