Comment (by kencu):

 Here is your error:

 {{{
 configure:4137: /usr/bin/clang -pipe -Os -arch x86_64 -I/opt/local/include
 -L/opt/local/lib -Wl,-headerpad_max_install_names -arch x86_64 conftest.c
 >&5
 dyld: Library not loaded: /opt/local/lib/libxml2.2.dylib
   Referenced from: /opt/local/libexec/llvm-9.0/lib/libLLVM.dylib
   Reason: Incompatible library version: libLLVM.dylib requires version
 12.0.0 or later, but libxml2.2.dylib provides version 10.0.0
 }}}

 it looks like the version of libxml2 that the llvm-9.0 port was built
 against is much newer than the version of libxml2 that you have currently
 installed. The llvm-9.0 port at present requires at least version 12.0.0
 of the libxml2 dylibs.

 my installed libxml2 port ( libxml2 @2.10.4_1 ) provides version 13.0.0:

 {{{
 % otool -L /opt/local/lib/libxml2.2.dylib
 /opt/local/lib/libxml2.2.dylib:
         /opt/local/lib/libxml2.2.dylib (compatibility version 13.0.0,
 current version 13.4.0)
         ...
 }}}

 why don't you also have that? Have you done something to force libxml2 to
 be an older version?

 please check this:
 {{{
 port -v installed libxml2
 }}}
