I personally would like to see Clozure CL 1.5 (planned for May 2010 or  
so) require Leopard.  I will be quite surprised if Apple still  
supports Tiger then.

Meanwhile, it does work to build Leopard interfaces locally.

1. Build ffigen by following the instructions at: http://trac.clozure.com/openmcl/wiki/BuildFFIGEN
2. Edit ccl/darwin-x86-headers/cocoa/C/populate.sh to look like this:

if [ $# -eq 1 ]
rm -rf System Developer usr
CFLAGS="-isysroot ${SDK} -msse2 -mmacosx-version-min=10.5"; export  
h-to-ffi.sh ${SDK}/System/Library/Frameworks/Cocoa.framework/Headers/ 

3. Follow the instructions at <http://ccl.clozure.com/ccl-documentation.html#The-Interface-Translator

That's a bit more complicated that one might wish (which is why we  
bundle interfaces...)
