Hi,
Usually, I build PAM early, but this time, I decided not to, to check
dependencies. And building cups-2.2.7, I receive:
-------

--------------
The "cups_crypt" function is only defined if HAVE_LIBPAM is 0. That's why this
error does not occur if pam is installed.
According to https://github.com/apple/cups/pull/5253 (which is about the
development branch), libpam will be made required for cups sooner or later.
So I suggest to recommend pam for cups right now (and require it when it
becomes mandatory).
Note that upstream has backported the change they made to address the issue in
their development branch, but I suspect one part of the backport has been
forgotten.
