Make error for TMVA: mac os 10.7.5


I just ran “make” under the /tmva/test of the root directory. It turned back with the error info of:

ld: 1059 duplicate symbols for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[1]: *** [lib/libTMVA.dylib] Error 1
make: *** […/lib/] Error 2

If anyone may tell me what’s going on here? thank you very much, i appreciate that.
