Build issue on OSX boost 1.77 json lib is not build.

Hi,

I have a mysterious issue where on OSX I try to build boost 1.77 with among
others the json component but it is not built. On linux there is no issue.
The same script builds everything fine.

Has anybody come across this by any chance ?
I could not find anything from a search on the net.

Thanks,
Jiri

Below are more details.
Using the commands listed below in the OSX case, the json lib is not built,
and on Linux it is.
Switching on more verbosity and using the -a -q -d 5 shows that json is in
the output, but not clear why it is not built.  This also seems to be the
case for 1.76, we tried this on multiple machines.
