I respect your adventure.
It's unfortunate that people are still using portacle.
It's 8 years old. It's #emacs build is not current, the build flags are ancient!
The packages do work, but there have been improvements in the last 8 years.
The emacs config is here. Crufty.
Slime, Company, Magit, Paredit and Ag.

Common lisp, #sbcl and #quicklisp are not difficult to install.
The portacle issues should give anyone pause.

Portacle doesn't do that much. I think it would be better to install things yourself so you know what you have and avoid the cruft.
My experience may give me a bad POV.
