You need 'apt-file' which you will probably need to install too as
it's not installed by default.  Then it's easy:-

    apt-file search <name of file>

Will provide the name of the package which provides the file.  You can
put a full path such as /usr/bin/qmake if just qmake produces too many
hits.

I've just done it for you:-

    chris$ apt-file search  /usr/bin/qmake
    gridengine-client: /usr/bin/qmake_sge     
    qtchooser: /usr/bin/qmake

So you need to install qtchooser.
