[Openmcl-devel] Coping with a name conflict

[martin]

Is the build to which Denis refers different from the CL 1.12 download on Github? 
And if so is it generally available?
(The link http://setf.clozure.com/~rme/ccl-1.12.1-ide-big-sur.zip <http://setf.clozure.com/~rme/ccl-1.12.1-ide-big-sur.zip> is broken.)
Thanks,
Martin
