Then they need to implement a packaging system that can prompt the user 
to resolve conflicts.  Apt does it by (using the example you gave) having 
each mta package provide "mail-transport-agent" but also conflict with 
"mail-transport-agent".  If the user installs something that depends on 
"mail-transport-agent" (e.g. mailx) and no installed package provides it 
then apt searches the package list for any package that provides it.  On 
finding multiple conflicting packages the user is prompted to resolve the 
conflict (and debconf records that choice for future reference, though 
the user may still be prompted in future depending on other preferences 
stored in debconf).  

Each such conflict is resolved until there are no ambiguities in the list 
of packages to be fetched, at which point the whole package list is 
fetched and installed.
