Dear all.

Installing geant4 with homebrew I get the following error:
Undefined symbols for architecture x86_64:
  "__ZTWN14G4GeomSplitterI8G4LVDataE6offsetE", referenced from:
      G4Track::CalculateVelocityForOpticalPhoton() const in
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[2]: *** [BuildProducts/lib/libG4track.dylib] Error 1
make[1]: *** [source/track/CMakeFiles/G4track.dir/all] Error 2
make: *** [all] Error 2

When doing "> brew doctor" I get many warnings, mostly on header files, which I attach separately.

Other infos: MacOs 10.12.1 incagli% gcc -v gcc: warning: couldn't understand kern.osversion '16.1.0 Using built-in specs.
