perl bindings to Xapian::Query

[Alex Aminoff]

QueryParser is great, but I would like to make a query myself, so I can 
filter results by a specified value (in this case restricting by epoch 
time after a certain value)

My code looks like this, and compiles, and appears like it should work 
according to the perl source:

     my $query = $qp->parse_query($querystr);

     if ($datefilter) {
         my $filterepoch = time() - ($datefilter * 60 * 60 * 24);
         my $filterquery = 
Xapian::Query->new(OP_VALUE_GE,I_DATE,$filterepoch);
         $query = Xapian::Query->new(OP_FILTER,$query,$filterquery);
     }

This appears to die on Xapian::Query->new with

   No matching function for overloaded 'new_Query' at 
/usr/local/lib/perl5/site_perl/Xapian.pm line 1282.

I see in Xapian.pm where Xapian::Query attempts to call 
Xapianc::new_Query . Is there some other way I am supposed to do this?

I should say that I am using xapian-bindings-1.4.4 which I compiled and 
installed myself.

Thanks,
