The latest x11-wm/i3 port does not install all the necessary files/scripts.

From http://i3wm.org/downloads/RELEASE-NOTES-4.1.txt:
 Introduce the i3-sensible-{pager,editor,terminal} scripts to execute
    $PAGER, $EDITOR or an available terminal emulator

These are not installed and causes i3 to not fully work. In my case, i3 was non responsive at all and required a kill.
I've copied them manually from the work directory of the port or local/bin/ and everything works fine.


Missing files afaik are:
work/i3-4.1/i3-sensible-editor
work/i3-4.1/i3-sensible-pager
work/i3-4.1/i3-sensible-terminal
 and their man pages.

Fix: Manually copy the files from work ${WRKSRC} or patch Makefile:
I've attached a diff of my "hacked" Makefile, it seems to work.

/usr/ports/x11-wm/i3/work/i3-4.1/Makefile lists all the needed files, and running gmake in that dir installs them but to /bin instead of local/bin:

install: all
        echo "[i3] INSTALL"
        $(INSTALL) -d -m 0755 $(DESTDIR)$(PREFIX)/bin
        $(INSTALL) -d -m 0755 $(DESTDIR)$(SYSCONFDIR)/i3
        $(INSTALL) -d -m 0755 $(DESTDIR)$(PREFIX)/include/i3
        $(INSTALL) -d -m 0755 $(DESTDIR)$(PREFIX)/share/xsessions
        $(INSTALL) -m 0755 i3 $(DESTDIR)$(PREFIX)/bin/
        $(INSTALL) -m 0755 i3-migrate-config-to-v4 $(DESTDIR)$(PREFIX)/bin/
        $(INSTALL) -m 0755 i3-sensible-editor $(DESTDIR)$(PREFIX)/bin/
        $(INSTALL) -m 0755 i3-sensible-pager $(DESTDIR)$(PREFIX)/bin/
        $(INSTALL) -m 0755 i3-sensible-terminal $(DESTDIR)$(PREFIX)/bin/
        test -e $(DESTDIR)$(SYSCONFDIR)/i3/config || $(INSTALL) -m 0644 i3.config $(DESTDIR)$(SYSCONFDIR)/i3/config
        test -e $(DESTDIR)$(SYSCONFDIR)/i3/config.keycodes || $(INSTALL) -m 0644 i3.config.keycodes $(DESTDIR)$(SYSCONFDIR)/i3/co
nfig.keycodes
        $(INSTALL) -m 0644 i3.welcome $(DESTDIR)$(SYSCONFDIR)/i3/welcome
        $(INSTALL) -m 0644 i3.desktop $(DESTDIR)$(PREFIX)/share/xsessions/
        $(INSTALL) -m 0644 include/i3/ipc.h $(DESTDIR)$(PREFIX)/include/i3/
        for dir in $(SUBDIRS); do \
                $(MAKE) -C $$dir install; \
        done
