Many thanks Jurgen; I'll give that a go. Just to be clear to me, if I was starting from scratch I'd need:

./bootstrap.sh --prefix=/gpfs/apps/boost/v1.59.0_gcc-v5.2.0 \
   --without-icu --with-python=$PYTHON_ROOT \
   2>&1|tee ../logs/bootstrap-`date +%y_%m_%d_%Hh%Mm`.log
time ./b2 install --without-mpi \
   --build-type=complete --layout=tagged -- cxxflags=-fPIC \
   --build-dir=../boostbuild \
   2>&1|tee ../logs/b2_install-`date +%y_%m_%d_%Hh%Mm`.log

Regards

You just have to recompile the static libraries with -fPIC enabled. Add 
cxxflags=-fPIC to your commandline and rebuild everything (either b2 clean or 
add -a to force recompilation).
Yours,
Jürgen
