Roswell is a Lisp implementation installer/manager, launcher, and much
more! It started as a command-line tool with the aim to make installing
and managing Common Lisp implementations really simple and easy. (https://roswell.github.io/)
There is a problem when installing Roswell using homebrew.
$ brew install roswell
$ ros setup
It fails to load sb-posix.
I couldn't found a solution and started to look into sbcl installation document and scripts.
I managed to fix the problem with following steps.
1. Go into sbcl source folder.
$ cd ~/.roswell/src/sbcl-2.2.2-arm64-darwin/
2. Run install.sh. it will copy fasl files to binary folder
$ INSTALL_ROOT=~/.roswell/impls/arm64/darwin/sbcl-bin/2.2.2 bash install.sh
