Comment (by ryandesign):

 The problem isn't caused by a new revision of the alps port. It's caused
 by using a newer compiler. The old version of the boost library contained
 within alps contains a programming mistake that old compilers allowed with
 just a warning. New compilers like the version of clang in Xcode 15.3 and
 later consider this mistake to be an error. The problem can be worked
 around by using an older compiler or by downgrading the warning back to an
 error. Instead of either of those, we should fix the port by correcting
 the programming mistake e.g. possibly by upgrading to a newer version of
 alps which may contain a newer version of boost that no longer has this
 mistake.
