how do you force make install to overwrite conflicting files from another port?

When you do the 'pkg delete -f PortA' then it will also delete the 
libraries installed by PortA.
if you do 'cd ...PortB; make install' and it will now install the files 
that were in conflict,
but there are now some libraries installed by PortA which are missing.

I understand that this is on the outskirts of package/port management,  
but there are times when
you want to install a test version of a utility which has only part of 
the functionality of another port.
