The steps I took:
1. Add 'CFLAGS+=-pg' to /etc/make.conf
2. cd /usr/src/usr.sbin/pkg_install && make obj && make depend &&
make clean && make
4. The profiled pkg_foo executables now reside in the corresponding
/usr/obj/usr/src/usr.sbin/pkg_install/foo directories. For pkg_info,
that would be .../pkg_install/info/. You can run them from there
(that's what I did) or 'make install' to put them in /usr/sbin/.
5. sudo /usr/obj/usr/src/usr.sbin/pkg_install/info/pkg_info -a >/dev/null
That will leave a pkg_info.gmon in /var/db/pkg/<last port name>/ (due
to the chdir(2) thingie I mentioned earlier).
6. gprof /usr/obj/usr/src/usr.sbin/pkg_install/info/pkg_info
/path/to/pkg_info.gmon
