Dyalog recently changed its distribution policies and licensing approaches to the APL interpreter, so it's easier than ever to get started on any platform.
I would encourage you to leverage this to write a Gentoo portage (or whatever they are using now) build for it yourself and send it out for the world. We have a number of Nix users that come to our APL workshops who have arranged for just such a system on Nix.
For typing the APL symbols, I use this: 'setxkbmap -layout us,apl -variant ,dyalog -option grp:lswitch'. I find this to be the most efficient for typing APL. The APL keyboard map comes default on modern Linux distributions.
Dyalog APL also has extensive documentation for configuring your APL system on your platform.
