A recent commit (r4840) adds /opt/local/include to the -I paths and adds 
/opt/local/lib to the -L paths, so MLton should compile with either 
MacPorts or Fink.  The linker paths are 'biased' towards MacPorts, so if 
you have both around, you'll link against /opt/local/lib.

I wouldn't expect you to need to change anything but the top-level 
Makefile.  And, I think that defaulting to /usr/local for darwin is the 
right choice.  It's not worth the Makefile hackery to try to dynamically 
detect whether the user is using MacPorts or Fink or self-installed 
/usr/local.  Should someone decide to provide MLton as a MacPorts or Fink 
package, it should be very easy for them to maintain the patch that 
installs in the package appropriate location.
