If the modules is a pure Perl one (no XS code) and was not packaged at all to be distributed you simply put thw .pm file in the appropriate directory that for a strawberry perl installation can be similar to c:\strawberryperl\site\lib

If the module just define a package like MyNewShinyMod the above path will be enough. By other hand if the module define a package like My::NewShinyMod you need to create a folder named My in the above path and put the .pm file there.
