编译parsec-2.1的时候出现下面的错误信息：
installing man1/smime.1
smime.pod around line 272: Expected text after =item, not a number
smime.pod around line 276: Expected text after =item, not a number
smime.pod around line 280: Expected text after =item, not a number
smime.pod around line 285: Expected text after =item, not a number
smime.pod around line 289: Expected text after =item, not a number
POD document had syntax errors at /usr/bin/pod2man line 71.
make: *** [install_docs] 错误 255
原因：这是由于OpenSSL 1.0.1e 与 perl5.18 不兼容。
解决方法：
1.有人验证 安装perl 5.16 可以兼容，安排低版本perl 5.16可以解决问题。
2.删除 pod2man文件：
sudo rm /usr/bin/pod2man
