When I try to install rmagic with:
gem install rmagic
it gives error:
Building native extensions. This could take a while...
ERROR: Error installing rmagick:

I tried to search for problem and found that I am missing libmagickwand-dev. I tried to install it with:
sudo apt-get install libmagickwand-dev
but it raises error:
The following packages have unmet dependencies:
libmagickwand-dev : Depends: libmagickcore-dev (= 8:6.7.7.10-5ubuntu2) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
If I try to install it with:
sudo apt-get install libmagickcore-dev
it gives error:
The following packages have unmet dependencies:
libmagickcore-dev : Depends: librsvg2-dev but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
If I try to install it with:
sudo apt-get install librsvg2-dev
it gives error:
The following packages have unmet dependencies:
librsvg2-dev : Depends: libglib2.0-dev (>= 2.24.0) but it is not going to be installed
Depends: libgdk-pixbuf2.0-dev (>= 2.23.5-2) but it is not going to be installed
Depends: libcairo2-dev (>= 1.2.0) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
If I try to install libglib2.0-dev with:
sudo apt-get install libglib2.0-dev
it gives error:
The following packages have unmet dependencies:
libglib2.0-dev : Depends: libglib2.0-0 (= 2.36.0-1ubuntu1) but 2.36.0-1ubuntu2 is to be installed

E: Unable to correct problems, you have held broken packages.
If I install libglib2.0-0 with:
sudo apt-get install libglib2.0-0
it gives:
libglib2.0-0 is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
If I install libglib2.0-bin with:
sudo apt-get install libglib2.0-bin
it gives:
Reading package lists... Done
Building dependency tree
Reading state information... Done
libglib2.0-bin is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
Those 2 libs are installed but issuing again:
sudo apt-get install libglib2.0-dev
it gives same error:
The following packages have unmet dependencies:
libglib2.0-dev : Depends: libglib2.0-0 (= 2.36.0-1ubuntu1) but 2.36.0-1ubuntu2 is to be installed
Depends: libglib2.0-bin (= 2.36.0-1ubuntu1)
E: Unable to correct problems, you have held broken packages.
What could be problem here?
I am using Ubuntu 13.04, rbenv, ruby 2.0.0, if that matters.

try this out
first install imagemagick
sudo apt-get install imagemagick
and then
sudo apt-get install libmagickwand-dev
回答2:
Solution is to add ppa where those libs could be found.
Add PPA:
sudo add-apt-repository ppa:ricotz/testing
Then update package list:
sudo apt-get update
Finally install it with:
sudo apt-get install libmagickwand-dev

Try clearing your apt repository and removing any broken packages first:
sudo apt-get update
sudo apt-get autoclean
sudo apt-get clean
sudo apt-get autoremove
If the system identifies any broken packages, forcefully remove them (replace package_name with your own):
sudo dpkg --remove -force --force-remove-reinstreq package_name
Then reinstall any missing packages again.

You only need to install:
sudo apt-get install libmagickwand-dev

Here is the good example on this blog
The below command will solve your problem. It helped me to install rmagick.
sudo apt-get install libdjvulibre-dev libjpeg-dev libtiff-dev libwmf-dev libmagickcore-dev libmagickwand-dev libmagick++-dev

This worked for me:
- sudo apt-get install libcairo2=1.14.6-1 --reinstall
- sudo apt-get install libmagickwand-dev
- sudo gem install rmagick
