/usr/lib/vhost.so missing Solaris 5.10

Hi,

i have a solaris 5.10 machine on which i am getting below error while
executing cat command

ld.so.1: cat: fatal: vhost.so: open failed: No such file or directory
Killed

it is related to file vhost.so missing

Also when i did

ldd cat

result is as below

  
        libc.so.1 =>     /lib/libc.so.1
        libm.so.2 =>     /lib/libm.so.2
        /lib/libm/libm_hwcap1.so.2
        /platform/SUNW,SPARC-Enterprise/lib/libc_psr.so.1

In a old system where its working

ldd cat 

o/p is

 vhost.so =>      /usr/lib/vhost.so
        libc.so.1 =>     /usr/lib/libc.so.1
        libdl.so.1 =>    /usr/lib/libdl.so.1
        /usr/platform/SUNW,Ultra-Enterprise/lib/libc_psr.so.1
