75 ways to demystify DB2: #16: Resource Info: Supported Perl with DB2 on Windows.
As of now, DB2 on Windows supports ActivestatePerl (both 32bit and 64 bit) and Strawberry Perl (32 bit ONLY).
To get the 32 bit DBD::DB2 binaries supported with 32 bit Strawberry Perl, you must email email@example.com or contact IBM support for the required binaries.
64 bit Strawberry Perl is not supported yet.
