libTMVA.1[.so | .sl | .dl | .a | .dll] does not exist

I’ve been using ROOT 5.26/00 (on mac os X), which has TMVA 4.0.4, and only recently tried out TMVA, but right away get an error when I load ROOT:

I had built root on my laptop by,

tar -xzf root_v5.26.00.source.tar.gz cd root ./configure macosx --with-python-incdir=/Library/Frameworks/Python.framework/Headers/ --with-python-libdir=/Library/Frameworks/Python.framework/Versions/Current/lib/ make -j 3
so I’m guessing it didn’t build TMVA.
