This is the case with gcc.

You understand the definitions just fine. It's the bug that has you
confused ;-)
Gcc rightfully depends on binutils (it needs them to do certain compiles)
and should not be installed without also installing binutils.
If you install binutils first and then install gcc (as my list driven
script does) there is no problem.
Dselect fails to do this properly and dpkg complains when it is asked to
install gcc before dselect has installed binutils.
This is a bug in dselect, unless the installer who submitted it has
altered the state of the dependency screen that was presented for this
issue.
If binutils has been selected to be installed in response to gcc's
dependence then dselect is in error as to the order of opperations.
Hope that makes it more clear,
