install_driver(DB2) failed:

Hi.

I'm running XP SP3

Active Perl 5.14.2.1402

PPM 4.14

DBI 1.625

DBD::DB2 1.85

My connection -

      $dbh = DBI->connect ("dbi:DB2:Sort", "$ID", "$PW",
      {
         RaiseError => 1,
         PrintError => 1,
         AutoCommit => 1,
      }
      ) or die $DBI::errstr;

fails with -

install_driver(DB2) failed: Can't load 'c:/Perl/site/lib/auto/DBD/DB2/DB2.dll' for module DBD::DB2: load_file:The specified module could not be found at c:/Perl/lib/DynaLoader.pm line 191.
  at (eval 6) line 3
Compilation failed in require at (eval 6) line 3.
Perhaps a required shared library or dll isn't installed where expected
  at HyperMail/Includes.pm line 74

but c:/Perl/site/lib/auto/DBD/DB2/DB2.dll exists with today's date on it.  I have DB2_HOME set to C:\Program Files\IBM\SQLLIB\lib.  Does anyone know what I'm missing here?
