Comment (by tcwan):

 This can be worked around when building gnucash @3.1 by doing the
 following:

 1. sudo port select python python36
 2. cd /opt/local/lib; sudo ln -s
 /opt/local/Library/Frameworks/Python.framework/Versions/3.6/lib/libpython3.6.dylib
 .
 3. Possibly need do the same for libpython3.6m.dylib (I did it in any
 case)
 4. cd /opt/local/lib; sudo ln -s
 /opt/local/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/
 .
 5. (This is the weird part) cd /opt/local/lib; sudo mv python-2.7 old-
 python-2.7
 6. build gnucash @3.1
 7. (Restore python-2.7 path) cd /opt/local/lib; sudo mv old-python-2.7
 python-2.7
 8. sudo port select python [your default python]

 From the problem, I guess the gnucash configure script is not searching
 for the correct Python interpreter at the correct locations.
 In addition, Python 3.x Portfile should probably configure links to
 /opt/local/lib for the dylib and access to the 3.x site-packages
 directories.
