Newer Version of Protoc Error

[jdpric3]

I am trying to install lava on an EC2 instance, and I continue to get error about mismatched protocol buffer sizes. In particular, when trying to compile "plog.pb.cc" I receive,

 #error This file was generated by a newer version of protoc which is
  ^
plog.pb.h:13:2: error: #error incompatible with your Protocol Buffer headers. Please update
 #error incompatible with your Protocol Buffer headers.  Please update
  ^
plog.pb.h:14:2: error: #error your headers.
 #error your headers.

When running Running [/home/lava/lava/panda/src/build.sh] . . . it says I am using protobuff 2.6.1 which should be fine.
