What you are observing is one of the reasons we decided to provide our
own packages - namely, that building BIND with dnstap support on a
platform which does not readily supply all relevant build requirements
is a bit of a pain in the neck.  The reason your CentOS 7 build
succeeded is that EPEL 7 contains the required build dependencies for
dnstap support in BIND; EPEL 6 lacks these and thus the build fails.

You have two options here:

  - build without dnstap support, by using "--without dnstap",

  - make the build requirements available in the build environment, most
    likely by first building them from source as well (you can use the
    SRPMs in our Coprs for convenience), in this order:

     1. libevent
     2. fstrm
     3. protobuf
     4. protobuf-c

The development packages in our Coprs can only be used for building a
Software Collection [1].  Thus, installing them as they are will not
allow you to compile a non-SCL version of BIND with dnstap support.

Hope this helps!

[1]: unless you rebuild them using "--without scl", of course
