yum install ncurses-libs.i686 ncurses-devel.i686
解决 libncurses.so.5 is needed by FirebirdSS-2.1.6.18547-0.amd64

yum install compat-libstdc++-33.x86_64 compat-libstdc++-33.i686 compat-libstdc++-296.i686
解决 libstdc++.so.5 is needed by FirebirdSS-2.1.6.18547-0.amd64

思路：
首先找台没问题的服务器
find / -name libncurses.so.5
find / -name libstdc++.so.5

/lib/libncurses.so.5
/lib64/libncurses.so.5

/usr/lib/libstdc++.so.5
/usr/lib64/libstdc++.so.5

rpm -qf /lib/libncurses.so.5
ncurses-libs-5.7-3.20090208.el6.i686
rpm -qf /lib64/libncurses.so.5
ncurses-libs-5.7-3.20090208.el6.x86_64

然后 yum 相对应的rpm包，即可解决类似问题。
