1. simply use cxxflags= , not darwin/cxxflags
2. Use quotes around -fvisibility=hidden else bjam will split again at "="

something like cxxflags=" -fvisibility=hidden" should work.

add -d+2 or use -n to see the resulting command line. Check this for your 
flags.

Please post the resulting command line next time.
