Sounds like probably post-extract, post-patch, etc. blocks will need to be added to the port to do those additional steps.

I don't have a resource to refer you to specifically for this situation, unfortunately, beyond the usual "read the guide" and "look at other portfiles". However, maybe I can do a part of it for you to show you how.

You said these are optional packages. So they'll be implemented in the pari port as variants, I presume?

Could you file a ticket for one such variant? You can include the URLs for the files that need to be downloaded and explain what steps need to be done, and I can try to update the portfile for that.
