我的意见是：
sudo apt-get install libsdl1.2-dev libsdl-image1.2-dev libsdl-mixer1.2-dev libsdl-ttf2.0-dev
输出为：
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies.
libsdl-image1.2-dev : Depends: libjpeg-dev
Depends: libtiff4-dev but it is not going to be installed
libsdl1.2-dev : Depends: libglu1-mesa-dev but it is not going to be installed
Depends: libpulse-dev but it is not going to be installed
Depends: libxt-dev but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
我该如何解决？
