Comment (by easieste@…):

 Hmmm.  sbcl-1.2.15 builds (and runs) for me on OS X 10.11.

 Are you sure that you upgraded to XCode 7.0.1?  After my upgrade to OS X
 10.11, initially I didn't upgrade my XCode which produced weird errors in
 other ports.

 If others are having build failures, please post some "me too!"s so that
 we know that this is a more general problem.

 As for how to proceed to determine the differences, I'm a little at a loss
 on how to duplicate, so suggestions are welcome.
