I remember this from the SBCL docs: "Important: It is highly recommended that you run the make.sh script in either a very fast terminal such as xterm (the GNOME terminal and the OS X terminal are too slow) or that you run it in a detached GNU screen session (use C-a d to detach the session and screen -r to resume it).
