scallywag cygport fails to detect perl script runtime dependencies

[Brian Inglis]

Does cygport require perl modules to be installed as build dependencies 
in order to enable their detection as runtime dependencies for perl 
scripts in packages?

Yes.

See __list_deps in pkg_info.cygpart

I don't know how we could traverse from module to package otherwise 
(other interpreted languages e.g. python, etc., generally have the same 
issue).

I don't see this a huge problem, as these dependencies would probably 
need to be installed to run tests, if the package has any.

Yes, although the particular way of how this is done frequently produces
false dependencies (there is no distinction between optional and
required dependencies).  In principe you could also end up with missed
dependencies, although I know of no example for this.

Saw that under 'check_prog\sperl'.

So we need to do this for all interpreted language scripts with language 
module dependencies supported in cygport.

True: good point; ta!
