This is one of those note-to-self posts. For whatever reason, I nearly always forget to enable threads and unicode when I build SBCL. Threads are required by hunchentoot; I enable Unicode just for kicks.

Here's my build recipe for SBCL:

1. > git clone git://sbcl.boinkor.net/sbcl.git sbcl-git ./sbcl.git
2. > cd sbcl.git
3. > git checkout sbcl_1_0_18
4. Edit customize-target-features.lisp to enable the features you want.

    (lambda (features)
      (flet ((enable (x)
               (pushnew x features))
             (disable (x)
               (setf features (remove x features))))
        ;; Threading support, available only on x86/x86-64 Linux, x86 Solaris
        ;; and x86 Mac OS X (experimental).
        (enable :sb-thread)
        (enable :sb-unicode)))
   

5. > screen
6. > sh make.sh
7. detach screen from terminal while compiling -- too much output! Ctrl-a, d
8. > sudo INSTALL_ROOT=/opt/sbcl sh install.sh
