Comment (by ryandesign):

 Replying to [comment:9 mohd-akram]:
 > If I do `port info icu` it shows clang-19 as a build dependency, but if
 I do `port info` inside the icu directory I don't see it.

 Hm, yes I see that too (with clang-17 instead of clang-19). The PortIndex
 files are generated on a machine running OS X 10.11. Maybe the method that
 [source:macports-infrastructure/jobs/mprsyncup mprsyncup] uses to fake the
 OS version is insufficient; it just gives [source:macports-
 base/src/port/portindex.tcl portindex] different platform values in the
 `-p` flag.

 > I also don't understand why it depends on clang-17 for you Ryan instead
 of clang-19.

 I'm on macOS 12. MacPorts only offers clang 18 and later to macOS 13 and
 later:
