Ruby SWIG - Errors on build

[curt]

Building the ruby version on mac osx 10.10.5:

ruby 2.2.2
quantlib 1.6.1 (installed via 'brew install quantlib' and via the quantlib.org instructions)
swig 3.0.7
Not sure if there's an error on my side or it's not compatible with the versions I'm using. To isolate the issue I installed the RQuantLib package for R and it works within R. I also did the test compile for BermudanSwaption.cpp and it worked.

CODE BELOW:

ruby setup.rb wrap

swig -ruby -c++ -I../SWIG -o ./quantlib_wrap.cpp quantlib.i
SWIG:1: Warning 125: Use of the include path to find the input file is deprecated and will not work with ccache. Please include the path when specifying the input file.
