QtCreator错误；无法加载库；ProjectExplorer（2.6.82）

我尝试按照此处的说明安装新的Ubuntu Phone SDK：http : //developer.ubuntu.com/resources/app-developer-cookbook/mobile/currency-converter-phone-app/

不幸的是，当我运行Qt-Creator时，它说一堆插件无法加载：

Cannot load plugin because dependency failed to load: ProjectExplorer(2.6.82)
Reason: /usr/lib/x86_64-linux-gnu/qtcreator/plugins/QtProject/libProjectExplorer.so: Cannot load library /usr/lib/x86_64-linux-gnu/qtcreator/plugins/QtProject/libProjectExplorer.so: (libQt5Declarative.so.5: cannot open shared object file: No such file or directory)

说明中是否缺少步骤，我的设置有问题还是在12.10中不起作用？

跑：

sudo apt-get install libbotan*

有同样的问题。错误消息还包含答案。有一个失踪者libbotan*.so。因此，这是qtcreator软件包中缺少的依赖项问题。

sudo apt-get install libbotan-1.10-0
