Question:  I have a package which I am working on, and
it creates some empty subdirectories in its tree under
${PREFIX}.

I can uninstall the package successfully from the initial
"make install" only if those empty subdirs are listed in
the PLIST.

However, I can only uninstall the package successfully
from a subsequent "pkg_add pkg_name.tgz" if these empty
subdirs are NOT listed in the PLIST, since they are not
extracted by tar during pkg_add.

Did I miss something here?
