 I assume that we'll if and when you'll be wanting to package them
 (supposing they ever get published)?
 Sorry, is there a word missing in the second sentence ("we'll ... if")?  I
 don't have a reason to package KF5.

 Without looking at the PortGroup, perhaps the script(s) just need to be
 added to whatever is the base port that the others will always include.
 Ie any port that has a dependency on shared-mime-info will (if packaged)
 'inherit' the above postinstall script.  For example, a stand-alone
 installer for gramps3 (the genealogy program) will include a mime database
 update 'for free'.
