INDEX breakage in cups

[Colin Percival]

A recent commit by ahze broke the INDEX build:

"Makefile", line 54: Could not find
/usr/ports/print/cups-lpr/../../print/cups/Makefile.common
make: fatal errors encountered -- cannot continue
===> print/cups-lpr failed
*** Error code 1
Stop in /usr/ports.

I tried to fix this by unhooking print/cups-lpr from print/Makefile, but
this turns out to not help since other ports depend upon print/cups-lpr:

make_index: Unresolved dependency: /usr/ports/print/cups-lpr

Note that in PR ports/97782, which ahze's commit closed, it says
"Please note, that:
 * cups-lpr must be removed after this update",
but it doesn't say what to do about ports which depend upon cups-lpr.

Can someone fix this, or tell me what to do here?
