 The package in the example (libgnomeui) is indeed installed on the system
 as an automatic dependency with no options selected.
 pkg_info does *not* print an empty line in that case.  It prints nothing:
 nervous-energy!bad 162 % pkg_info -Q PKG_OPTIONS libgnomeui | od -x
 nervous-energy!bad 163 %

 Here is how to reproduce the behaviour with a makefile:
 nervous-energy!bad 167 % cat zorch
 FOO != true 2> /dev/null
 nervous-energy!bad 168 % make -f zorch
 make: "/tmp/zorch" line 1: warning: Couldn't read shell's output for "true 2> 
 nervous-energy!bad 169 %
