Missing memcache-store.so on Amazon Linux

[Mansoor Mirza]

Hi,

I have installed version 2.6.1 release 3.1.el6 on Amazon Linux, but at startup it complains about not finding memcache-store.so. Has this library been removed from the installation?

2018-04-11 15:03:46 INFO XMLTooling.Config : loading extension: memcache-store.so

Thanks!
