Updating OSX was unable to locate /usr/lib/libnetsnmp.25.dylib

Upgrading to the latest public Beta for OS X 10.10.5 will break the php and while I was trying to execute the snippet code from the php terminal I encountered the following messages:

$ arc diff
dyld: Library not loaded: /usr/lib/libnetsnmp.25.dylib
Referenced from: /usr/bin/php
Reason: image not found
Trace/BPT trap: 5

I checked the contents of the Library folder and discovered some changes to the Net-SNMP libraries:

ls -la /usr/lib/libnetsnmp.*
-rwxr-xr-x 1 root wheel 1106528 10 Sep 2014 /usr/lib/libnetsnmp.15.1.2.dylib

lrwxr-xr-x 1 root wheel 19 17 Jul 02:23 /usr/lib/libnetsnmp.dylib -> libnetsnmp.30.dylib

What solved the issue
Symlinking libnetsnmp.25.dylib to the latest version of libnetsnmp.dylibfixes the issue:

$ sudo ln -s /usr/lib/libnetsnmp.dylib /usr/lib/libnetsnmp.25.dylib

Still not sure why the php was not updated to match the system changes. The php version now says

$ php -v
