I too use Strawberry and use local::lib. To first get it "installed":

perl -Mlocal::lib
[download]

Not sure if I needed to create the C:\Users\VinsWorldcom\perl5 directory of if it did that for me. But when you run the above command, it prints out some environment variables to set and you can add them through Control Panel -> System so they're permanent. Then you can install modules in the C:\Users\VinsWorldcom\perl5 and your PERL5LIB environment variable path should have your local::lib directory at the beginning.

NOTE: If you're using Git for Windows bash, it comes with a perl which is *not* Strawberry and running perl from Git for Windows bash (at least for me) uses its local perl, *not* Strawberry.
