fomus will not compile in sbcl 0.9.0 on OSX:

; compiling (DEFPARAMETER +LILYPOND-DYNS+ ...) ; compiling (DEFUN SAVE-LILYPOND ...)set_auto_gc_trigger: tried to set gc trigger too high! (0x081a3e98) fatal error encountered in SBCL pid 1317: lost The system is too badly corrupted or confused to continue at the Lisp level. If the system had been compiled with the SB-LDB feature, we'd drop into the LDB low-level debugger now. But there's no LDB in this build, so we can't really do anything but just exit, sorry.

it does compile and load in cmu and openmcl.
