There you will see it is not a new problem … and not one that has been fixed.
Your options are basically to hack at the pkgbuild or to use downgrade on sip temporarily.
(as the package is only a ‘make depend’ - only needed to build the package, not use it)
Well, after your edit your commands are off now.
You only need the first one.
The second one would seemingly overwrite the ‘downgraded’ sip and reinstall the current version.
I guess we will wait for the next report though…
Fixed it to contain what I had to do to actually fix the problem.
I eventually ignored package updates for sip to stick to the one I wanted and got this (sorry, it takes a long time on my ancient machine to install nearly anything that requires make):
