Problem with installing DBD-Pg on Windows

Hi ,
I have istalled and working Perl on my Windows
Now I want to have and Postgres interface.
I downloded "DBD-Pg-2.10.0-Perl5.10.ppd" (because my Active Perl Version 
is 5.10), and I installed It.

    /C:\Perl\lib>ppm instal DBD-Pg-2.10.0-Perl5.10.ppd
    Downloading -Pg-2.10.0-Perl5.10.ppd ... done
    Unpacking -Pg-2.10.0-Perl5.10.ppd .... done
    Generating HTML for -Pg-2.10.0-Perl5.10.ppd ... done
    Updating files in site area ... done
    10 files updated/


*I wrote this script:
*

    /use strict;

    use DBI;

    my $dbh = DBI->connect("DBI:Pg:dbname=test; host=localhost:5432",
                            "postgres" ,
                            "aiFt7DDj") || die "Database connection not
    made: $DBI::errstr";
    $dbh->disconnect();/

*And I have this error:
*

    /install_driver(Pg) failed: Can't load
    'C:/Perl/site/lib/auto/DBD/Pg/Pg.dll' for module DBD::Pg:
    load_file:The specified module could not be found at
    C:/Perl/lib/DynaLoader.pm line 201.

    Compilation failed in require at (eval 4) line 3.
    Perhaps a required shared library or dll isn't installed where expected
     at C:/workspace/perl_DataBase.pl line 12/

*Can you help me, what i do wrong? Thank you!
Have a nice day
