Not part of the basic set-up, then.  There are packages that cannot 
ordinarily be installed together - the resolution is usually to choose 
just one of them.  If you used dselect to make the choices (which is how 
the basic installation does it) then it will try and make you resolve 
that at selection time.  If using apt directly, it expects you to change 
what you're telling it to do.  There options you can use to force things 
(e.g. --force-yes) but if you don't have the man-pages installed at that 
point you might not know that.

There are limits to how much forcing you can do with apt because it is a 
macro-manager.  dpkg is the rpm equivalent and for forcing installs where 
there are file-conflicts etc you should use that.  You can use apt to 
just download the package (apt-get install --download-only) and then use 
dpkg to do the nasties.

What often catches people out is that Debian comes with a preprepared 
list of packages to install.  They skip the package-selection part of the 
installation thinking that they will then keep the minimal set-up they 
have.  But the selections are still in place (because apt maitains state 
for packages) and will be processed next time either dselect or apt is 
run.
