Comment (by cjones051073):

 b.t.w. Could you please also post the *complete* output of *everything*
 you get when you run `make developer`. I mean everything. I specifically
 want to see how faust configures itself.

 when I do it I get this

 which is expected as we do not provide by default a `llvm-config` command
 in the default PATH in MacPorts. These are the versions that each of the
 llvm versions provides

 {{{
 Larissa ~/Projects/MacPorts/ports > port contents llvm-18 | grep llvm-
 config
   /opt/local/bin/llvm-config-mp-18
   /opt/local/libexec/llvm-18/bin/llvm-config

   /opt/local/libexec/llvm-17/bin/llvm-config
   /opt/local/libexec/llvm-17/include/llvm/Config/llvm-config.h
 }}}

 It is up to users to decide which they wish to use and configure their
 builds appropriately to use the correct version.

 My bet is whatever llvm-config your build is finding, it probably isn't
 one from MacPorts, and also quite likely not the correct version for LLVM
 17 or 18.
