Comment (by cooljeanius):

 Just checking back to note that the combination of disabling ocaml-ctypes
 plus turning on trace mode allowed my build of llvm-11 to succeed. Also,
 trace mode reports a bit more opportunistic port usage besides ocaml, too;
 after configure it says this:
 {{{
 Warning: The following existing files were hidden from the build system by
 trace mode:
   /opt
   /opt/local/bin/git
   /opt/local/bin/go
   /opt/local/bin/install_name_tool
   /opt/local/bin/ld
   /opt/local/bin/llvm-ar-mp-9.0

   /opt/local/libexec/llvm-11/bin/llvm-readelf
   /private/var/select/sh
   /usr/X11R6
 }}}
 And also, after snipping the nonexistent ones, this:
 {{{
 Warning: The following files inside the MacPorts prefix not installed by a
 port were accessed:
   /opt/local/bin/llvm-ar
   /opt/local/bin/llvm-ranlib
 }}}
 Some additional dependencies or conflicts-build entries to add? Not sure
 which of them it's good to have hidden and which it'd be ok to unhide...
