The easiest would be to install under cgi-bin (didn't you say that's the only place you can create directories?). But as long as you add use lib '/path/to/some/dir';, it doesn't matter.
No, you can't install any module this way. The module you asked about happens to be pure-perl, and just one source file. But it's not a general installation procedure by any means.
