Hey! The port mail/mu builds its Emacs extension mu4e, but it does not install it. I had to manually copy 'work/mu4e' into '/usr/local/share/emacs/site-lisp/' in order to be able to use mu4e.
I am not yet experienced in working with ports, so I am not (yet) able to provide a patch, but maybe it is easy for you to do so ;) Optionally, it would be nice, I guess, to provide a configuration option to build and install mu4e or not. Kind regards _1126 (Christian)
