My first thought was: 

$text =~ s/(?:national security adviser |dr\. |doctor |condoleeza )+ri
+ce/condoleezarice/ig;

But that is not what you want. You want exact. So ... we need to get down to the tricky stuff ... ;-)

$text =~ s/(?!rice)
           (?:dr\.\ |doctor\ )?
           (?:condoleeza\ )?
           rice
          /condoleezarice/igx;

I just love trickery! :-)

The Sidhekin proves Sidhe did it!
