It is obvious that the package give in the example uses the options framework.

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 %

ISTR that I tested it under these conditions too and I saw the same error.
However, I can't reproduce it now.
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 %
