Comment (by cave-canem):

 Hello Ken!

 I seem to have found a bug (Heisenbug).

 I built dav1d with mp-clang-devel (clang 13.0.0) and cctools @ 949.0.1_1
 +llvmdev.

 So, the point is cctools @ 949.0.1_1 +llvmdev:


 {{{
 which -a otool
 /opt/MacPorts/bin/otool
 /usr/bin/otool
 }}}


 {{{
 ls -l /opt/MacPorts/bin/otool
 lrwxr-xr-x  1 root  wheel  10 Jul 12 20:38 /opt/MacPorts/bin/otool ->
 llvm-otool
 }}}


 {{{
 otool -L /opt/MacPorts/lib/libdav1d.5.dylib
 llvm-objdump: Unknown command line argument '-macho'.  Try:
 '/opt/MacPorts/libexec/llvm-devel/bin/llvm-objdump --help'
 llvm-objdump: Did you mean '-h'?
 llvm-objdump: Unknown command line argument '-dylibs-used'.  Try:
 '/opt/MacPorts/libexec/llvm-devel/bin/llvm-objdump --help'
 llvm-objdump: Did you mean '--dylibs-used'?
 llvm-objdump: Unknown command line argument '-non-verbose'.  Try:
 '/opt/MacPorts/libexec/llvm-devel/bin/llvm-objdump --help'
 llvm-objdump: Did you mean '--non-verbose'?
 }}}


 {{{
 /usr/bin/otool -L /opt/MacPorts/lib/libdav1d.5.dylib
 /opt/MacPorts/lib/libdav1d.5.dylib:
         @rpath/libdav1d.5.dylib (compatibility version 5.0.0, current
 version 5.0.0)
         /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current
 version 1197.1.1)

 }}}

 If you select mp-clang-devel and '''cctools @ 949.0.1_1 +llvm10''' when
 building libdav1d, then:


 {{{
 otool -L /opt/MacPorts/lib/libdav1d.5.dylib
 /opt/MacPorts/lib/libdav1d.5.dylib:
         /opt/MacPorts/lib/libdav1d.5.dylib (compatibility version 5.0.0,
 current version 5.0.0)
         /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current
 version 1197.1.1)
 }}}

 and everything is being '''built correctly'''.
