Not all all true. Builds from source works just fine, I in fact do it 
all the time for all ports, as we do not yet have *any* binary tarballs 
for macOS15 arm

isl also builds just fine on pretty much all platforms

https://ports.macports.org/port/isl/details/

why its failing for you is hard to say as you have not provided enough 
information really to comment.

If you are on macOS14, but do not have a consistent SDK under /Library/
 > Developer/CommandLineTools/SDKs then *your* installation is a bit 
messed up. You should look into reinstalling your CLT using the correct 
version for your OS.
