What do you mean by "doesn't work"?  I have used something similar for a
long time, and it works for me.  However, sudo doesn't work well when
${HOME} or ${SHELL} don't exist, so I also test for them.  Here's
the relavent part of my mk.conf file:

.if exists(${SHELL}) && exists(${HOME})
.  for _sudo_cmd in ${LOCALBASE}/bin/sudo /usr/pkg/bin/sudo /usr/local/bin/sudo
.    if exists(${_sudo_cmd})
SU_CMD?=${_sudo_cmd} /bin/sh -c            # requires security/sudo package
.    endif
.  endfor
SU_CMD?=/usr/bin/su -m root -c  # "su -m" does not clobber environment
.endif

There's no cyclic dependency.  Because if the ".if exists" test, sudo
won't be used if it's not already installed.
