我在 Ubuntu 15.10 上。我安装了软件包libboost-program-options1.58-dev，libboost-all-dev但是库本身显然不存在：
$ sudo find / -name libboost_program_options
仅存在的 boost 库包括：
$ l /usr/lib/x86_64-linux-gnu/ | grep libboost
-rw-r--r-- 1 root root 67K Oct 14 15:53 libboost_date_time.so.1.58.0
-rw-r--r-- 1 root root 95K Oct 14 15:53 libboost_filesystem.so.1.58.0
-rw-r--r-- 1 root root 95K Oct 14 15:53 libboost_iostreams.so.1.58.0
-rw-r--r-- 1 root root 15K Oct 14 15:53 libboost_system.so.1.58.0
我在使用某些程序时遇到以下错误：
$ vera++
vera++: error while loading shared libraries: libboost_program_options.so.1.58.0: cannot open shared object file: No such file or directory
FAIL
这些包裹出了什么问题？
更新：
$ apt-cache policy libboost1.58-dev
