Sorry, I forgot that the "checking if R installation supports OpenMP
without any extra hints" test only happens on Linux. Looks like the
current ./configure will always add -lomp to PKG_LIBS and break the
build unless you're running Xcode <= 16.2.
If you're interested in testing a development version of data.table,
could you please try compiling from the 'fix-macos-15-image' branch?
