Does this really work? If I require for gl2ps:

$ pkg_info -S gl2ps
Information for gl2ps-1.4.2nb2:

Size in bytes including required pkgs: 3173577

But:

$ pkg_info gl2ps
Information for gl2ps-1.4.2nb2:

Requires:
tex-latex-bin-[0-9]*
freeglut>=3.2.2nb1
png>=1.6.0nb1

$ pkg_info -S tex-latex-bin
Information for tex-latex-bin-2020:

Size in bytes including required pkgs: 7626672

How can a package depending on tex-latex-bin be said to need only
3173577 bytes, dependencies included, when one of the dependency is
7626672? ;-)
