I had some thoughts about this very subject posted to a different forum.

We spend a lot of effort with modules, verifying that all files are present, they work, etc. before putting them live.

What about their poor relations, the scripts? A script writer could implement tests in an equivalent of make test. The install step could copy to cgi-bin or wherever the script needs to go, changing the shebang line in the process, having worked out where perl lives.

Could Extutils::MakeMaker be used to do this, or is this too hard-coded for modules and h2xs?
