Some ports use user-settable options that start with USE_*. These are reserved
for bsd.port.mk and friends, and may give strange results when defined on the
command line or in make.conf. For example:

  cd security/gnupg; make install USE_OPENLDAP=yes

fails when OpenLDAP is not installed, but succeeds when OpenLDAP is installed.
