run "./gazebo-arm.sh", error raised, "This program requires version 3.5.0 of the Protocol Buffer runtime library"

[ababycat]

The project can complied completely, but when I run this "gazebo-arm.sh" or "gazebo-rover.sh" in the command line, it got errors. When I run "gazebo-arm.sh", it print the error bellow. And then I removed protobuf(2.6.1), and installed a protobuf(version 3.5.0), the project couldn't make well, that gazebo7 use protobuf (2.6.1), so I remove protobuf(3.5.0), and re-installed protobuf(2.6.1). The error still exists. I don't really know where got the error This program requires version 3.5.0, which program use "3.5.0"? Do someone meet this error?

Thank you!
