[Bioperl-l] install problems?

[george]

I am trying to use the BPlite module of bioperl w/ the script
in the tutorial.

   use Bio::Tools::BPlite;
   $report = new BPlite(-fh=>\*STDIN);
   $report->query;
   while(my $sbjct = $report->nextSbjct) {
        $sbjct->name;
        while (my $hsp = $sbjct->nextHSP) { $hsp->score; }
   }


I get the message :

#Can't locate object method "new" via package "BPlite" at 
./testbplite.pl line 4.

when i run the parse_blast2.pl script in the examples folder it runs correctly
until it gives a error message of

Can't find the object method "layout" via package Bio::Seq at 
parse_blast2.pl line 135, <STDIN> chunk 3.

Have I installed bioperl correctly? Do I need additional modules?
redhat 6.2, perl 5.005

Any advise would be appreciated

Thanks
