Unmet dependencies while installing OpenCV

[nickoppen]

I've been attempting to install OpenCV using methods from a number of different sources. Regardless of what the method is I always seem to get the following:

The following packages have unmet dependencies:
libopencv-dev : Depends: libopencv-objdetect-dev (= 2.4.8+dfsg1-2ubuntu1) but it is not going to be installed
Depends: libopencv-highgui-dev (= 2.4.8+dfsg1-2ubuntu1) but it is not going to be installed
Depends: libopencv-legacy-dev (= 2.4.8+dfsg1-2ubuntu1) but it is not going to be installed
Depends: libopencv-contrib-dev (= 2.4.8+dfsg1-2ubuntu1) but it is not going to be installed
Depends: libopencv-videostab-dev (= 2.4.8+dfsg1-2ubuntu1) but it is not going to be installed
Depends: libopencv-superres-dev (= 2.4.8+dfsg1-2ubuntu1) but it is not going to be installed
Depends: libopencv-ocl-dev (= 2.4.8+dfsg1-2ubuntu1) but it is not going to be installed
Depends: libcv-dev (= 2.4.8+dfsg1-2ubuntu1) but it is not going to be installed
Depends: libhighgui-dev (= 2.4.8+dfsg1-2ubuntu1) but it is not going to be installed
Depends: libcvaux-dev (= 2.4.8+dfsg1-2ubuntu1) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

I don't understand how the linux package system works. Is this a problem on my side or is there a database out there somewhere that wired correctly?

Thanks Andrew. That did the trick. The only thing that aptitude threw up that seemed to be odd was that one package needed to be downgraded. After I applied that fix it went in ok as far as I can see.
