【问题描述】：
我正在尝试在 Debian 7.6 (Wheezy) 上安装 redmine 2.5.4。我遇到了一个问题，为什么我尝试安装 rmagick gem。
我尝试了apt-get install libmagickwand-dev libmysqlclient-dev 和apt-get install libmagick++-dev，但我无法安装。确实，之后出现了冲突：
maxime@ns504687:/opt/redmine$ sudo aptitude why-not libmagick++-dev
i imagemagick Suggests html2ps
p html2ps Depends perlmagick
p graphicsmagick-libmagick-dev-compat Provides perlmagick
p graphicsmagick-libmagick-dev-compat Conflicts libmagick++-dev
这是apt-get install libmagickwand-dev libmysqlclient-dev的结果
maxime@ns504687:/opt/redmine$ sudo apt-get install libmagickwand-dev libmysqlclient-dev

libmysqlclient-dev is already the newest version.
libmysqlclient-dev set to manually installed.

我尝试了很多在网上找到的解决方案，但没有一个奏效。
你能帮帮我吗？
