I think it's much better to avoid tweaking ${STRIP} and set DEBUG_FLAGS
instead.  You have to make sure that at least the claws-mail-2.7.2 port
is *rebuilt* from source.  The following should work fine:

    # cd /usr/ports/mail/claws-mail
    # make deinstall
    # env DEBUG_FLAGS='-ggdb' make install

The STRIP variable is explicitly set to an empty value when DEBUG_FLAGS
is defined, so you get both a debugging *and* non-stripped binary by
setting DEBUG_FLAGS.
