py_environment.cpp "list" is ambiguous

[alan@…]

I'm seeing the following using PGI 12.2 on Cray Linux 4 (SuSE 11 derivative):

    "CC" -INLINE:none --gnu -Kieee -fpic -fPIC -gopt -Minform=warn -DBOOST_ALL_NO_LIB=1 -DBOOST_MPI_DYN_LINK=1 -DBOOST_MPI_PYTHON_DYN_LINK=1 -DBOOST_PYTHON_DYN_LINK=1 -D__need_IOV_MAX -I"." -I"/apps_hpc/epd/default/include/python2.7" -c -o "bin.v2/libs/mpi/build/pgi/debug/boost.locale.icu-off/python/py_environment.o" "libs/mpi/src/python/py_environment.cpp"

2 errors detected in the compilation of "libs/mpi/src/python/py_environment.cpp".

Not concerned about the warning from my header (didn't want to edit it out though), but it looks to me like maybe one of the other list classes has found it's way into the namespace?

These particuliar builds were bootstrapped and run with

./bootstrap.sh --without-icu --with-libraries=mpi,graph_parallel,python --with-python=##EDITED## --with-python-root=##EDITED## --with-python-version=2.7 --with-toolset=pgi

./b2 -d0 -d+2 -j32 --debug-configuration --disable-icu boost.locale.icu=off -sNO_BZIP2=1 --build-type=complete --layout=tagged threading=single variant=debug toolset=pgi install

Could you try to make it work by inserting ::boost:::python:: and then send me the patch?

This diff resolved the issue for me. Also appears to work fine with the other compilers available to me.
