I'm not sure if this is possible, but if it is, it would be quite helpful to me.

I'd like to know if there is a way to detect the name of a perl program which has imported a given perl module within that module, so that the information on module usage can be logged to a file.

Basically, I'd like to reverse-engineer which modules are being used by which programs in production; one way would be to drop in a module which logs the name of it's calling program every time it is used. After a period of time (several weeks/months) the typical usage pattern could be detected.

The other option I can think of involves something conceptually along the lines of: 

for module in <list of modules to investigate>;do 
    grep $module `find / | xargs file | grep Perl | cut -d":" -f1`  
done

which will probably be slow no matter how I code it.

Suggestions?
