How I can check which system libraries I need for my gems ?
For example the Mysql gem needs the mysql header files, rmagick requires imagemagick, and so on...
How I can list all libraries needed to install the gem ?
If it is not possible, how I can check if all system dependencies are satisfied to install the selected gem ?

Use the gem dependency GEMNAME command.
See the documentation here.
