error in package installation
 

i was installing some C/C++ plug-ins for codelite IDE before actually installing Codelite IDE(from the .deb packege available), and the installation didnt complete successfully, it left errors in the system. now evrytime i install something from terminal i get following error and the application doesnt get installed.
i am a newbie to linux and ubuntu, so i dont knw how to remove some packages or to restore the system from last restore point before this errors started, what i shud do to resolve this problem.
following, is just an example:

preetam@ubuntu:~$ sudo apt-get install mplayer

in this case, the mplayer is not installed, and this error appears...and same way if i try to remove codelite, then also it gives errors, so is there any way to remove all these packages which caused problems...? please help.

another case:::

preetam@ubuntu:~$ sudo apt-get remove codelite
