I am trying to install lispbuilder-SDL on Linux using the instructions given here. I have gotten to the part where I must install CFFI using ASDF but I am getting the following error when I try to type (require 'asdf-install):
Don't know how to REQUIRE ASDF-INSTALL. [Condition of type SB-INT:EXTENSION-FAILURE]
What do you suggest I do next? I tried looking it up but I found nothing helpful and I am new to all of this. Thanks!
