Different .so dependencies between normal build and RPM

With 1.10.x, I'm able to build the two RPMs, but when installing, there's a dependency for libwiretap.so.2 and libwsutil.so.2, even though the build directory contains only the .so.3 varieties. The RPM won't install without these. If I force the install and do an "ldd wireshark" on the executable, it claims to need both the .so.3 and the .so.2 varieties

When I do a "make install" and run an ldd on the /usr/local/bin/wireshark executable, it only has a requirement for the .so.3 varieties.

I do not know enough about the build process to know what is informing the RPM build that wireshark needs the .so.2's. Perhaps there's the Makefiles in the packaging/rpm directory are not sync'd with the toplevel Makefile's more recent changes?
