-rdynamic on GCC instructs the compiler to add symbols it normally wouldn't add to the resulting .so. On OSX, the g++ you are most likely using is the Apple front end to Clang supplied with XCode and NOT g++. -soname is used to mark your library's compatibility e.g. if you link against libzmqpp.so.3 and later deploy libzmqpp.so.3.1 you app would still be able to link against the 3.1 version. Clang on OSX doesn't AFAIK support -rdynamic or -soname (for one thing they are dylibs no so's) options as such.
I haven't tried compiling the project in question, but most likely to use the makefile AS IS you will need to get a real (ie. not part of XCode) GCC installed. You can follow these instructions to build it - http://solarianprogrammer.com/2013/06/11/compiling-gcc-mac-os-x/ It also looks like Homebrew has a formula for GCC as well.
