I installed qtspim which requires qt4 to be installed. As I already have qt5 installed on my system, qtspim is working fine.

However, Software Center reports dependency error. When I run apt-get check it gives:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
 qtspim : Depends: qt4-dev-tools (>= 4.7) but it is not installed
      Depends: qt4-doc (>= 4.7) but it is not installed
E: Unmet dependencies. Try using -f.

I don't want to install qt4 as i already have the latest version installed.

No

you have to install qt4 libs for running qt4 programs, qt5 is not 100% backward compatable with qt4

Thanks for the answer. Can you provide a reference about this. –  Anwar Shah Jan 19 '13 at 17:48
    
@Anwar: The name of the shared libraries are different and therefore an application that links to the Qt4 libraries will run only if the Qt4 libraries are present. –  Nathan Osman Feb 5 '13 at 21:21
