Can't use gurobi on Debian 9 (undefined symbol)

[jonglezb]

I installed Gurobi 5.6.3 as explained in the doc: extract it, then set GUROBI_HOME, then build/install Numberjack. I also had to set LD_LIBRARY_PATH at runtime so that the lib is found:

GUROBI_HOME="$HOME/tmp/gurobi/gurobi563/linux64"
LD_LIBRARY_PATH=$GUROBI_HOME/lib

However, when trying to solve a problem with Numberjack using Gurobi, I still get

ImportError: /usr/local/lib/python3.5/dist-packages/_Gurobi.cpython-35m-x86_64-linux-gnu.so: undefined symbol: _ZNK12GRBException10getMessageB5cxx11Ev
