If you are missing dependencies, there is also
Bundle::DBD::DB2 that includes them as well. If that doesn't install, you could try downloading the tarball (.tar.gz file) by clicking on the breadcrumb in front of the above name, and then on the download link and the file will download. Use 7-zip or similar archive software to extract firstly from the .gz and then extract again from the resulting .tar file, then in a DOS prompt:
cd to where you extracted from .tar, then
perl Makefile.PL
dmake
dmake test
dmake install
