A very excellent suggestion and certainly part of the story, thank you :)

My understanding is that install_script will perform all of the necessary work to install the various additional scripts.

Is there a way to additionally include the execution of distname_any-file.pl as part of the make install procedure?

Perhaps it's easier with a working example to explain what I am doing (disclaimer: I have substituted my project name for the standard Catalyst tutorial myapp):

Leaning on the advice of another reply to my original post (and to keep this explanation as simple as possible), I have created a database directory called database in the root directory of the project (so it's a sibling of script, root, lib, etc.), with the database update-upgrade script myapp_database.pl, and a directory called sql containing the necessary SQL files. The relevant part of the output of tree -fi is:

./database
./database/myapp_database.pl
./database/sql
./database/sql/create-tables.sql
./database/sql/create-data.sql
[download]

My Makefile.PL now also includes:

install_script glob('database/myapp_database.pl');
install_share  ( 'dist', 'database/sql');
[download]

This nicely places the script and the SQL files in sensible places within the blib directory (genuinely impressed at how easy this was!)

What I would like to do at this point is add something like:

post_install_execute 'myapp_database.pl';

Is this, or something equivalent, possible?

Thank you again!
