Comment (by ryandesign):

 The config.log shows that the reason is:
 {{{
 dyld: Library not loaded: /opt/local/lib/libffi.7.dylib
   Referenced from: /opt/local/libexec/llvm-7.0/lib/libLLVM.dylib
   Reason: no suitable image found.  Did find:
         /usr/local/lib/libffi.7.dylib: stat() failed with errno=13
 }}}
 So the problem is that libffi was updated to a new version that provides
 libffi.8.dylib (not libffi.7.dylib like it used to), and your llvm-7.0
 port hasn't been updated yet. Update it first.
 {{{
 sudo port upgrade llvm-7.0
 }}}

 If you do have /usr/local/lib/libffi.7.dylib as the error message says,
 that is not recommended; see wiki:FAQ#usrlocal.
