I am using using Centos 6.6 and there is a shared library the build generates used by number of executable and any executable using this shared library cannot find it as seen by ldd. I can locate the library:

$ locate libcs.so.1
/opt/cloudshield/lib/libcs.so.1

ldd shows the following:

$ sudo ldd /opt/cloudshield/lib/libcs.so.1
ldd: warning: you do not have execution permission for `/opt/cloudshield/lib/libcs.so.1'
    linux-vdso.so.1 =>  (0x00007ffff4fff000)
    libc.so.6 => /lib64/libc.so.6 (0x00007f7a0fd56000)
    /lib64/ld-linux-x86-64.so.2 (0x000000340ba00000)

$ sudo ldconfig -v | grep libcs.so.1

Is it because of the kernel library linux-vdso.so.1?

Executable cannot find the library libcs.so.1:

Add /opt/cloudshield/lib/ to your LD_LIBRARY_PATH environment variable, e.g.: 

LD_LIBRARY_PATH=/opt/cloudshield/lib
export LD_LIBRARY_PATH
