Error installing mencached plesk 12.5 CentOS 6.7

I upgraded to plesk 12.5 in CentOS 6.7

When I try to install mencached following instructions: http://devblog.plesk.com/2015/08/adding-custom-php-modules-in-plesk/
I get this error:

configure: error: no, sasl.h is not available. Run configure with –disable-memcached-sasl to disable this check
ERROR: `/tmp/memcached/configure –with-libmemcached-dir=no’ failed

I’ve tried different solutions searching the web, but none has worked.

Any ideas?
