I am trying to install pyamg in my virtual environment. However, I am getting the following error. I am using mac OS.
c++: pyamg/amg_core/amg_core_wrap.cxx
clang: error: no such file or directory: '“-I/Users/mas/PycharmProjects/kaggle-ndsb/boost_1_59_0”'

Actually, I think @oarfish called it correctly in the comments. The problem seems to be the funny “ and ” characters in those paths, which are distinct from the usual " double quote symbol.
The following reproduces the error for me:
~$ CPPFLAGS=“-I/Users/mas/PycharmProjects/kaggle-ndsb/boost_1_59_0” \
LIBS=“-L/Users/mas/PycharmProjects/kaggle-ndsb/boost_1_59_0/stage/lib” \
pip install pyamg

Whereas with " symbols the installation succeeds:

The paths themselves are irrelevant - the compilation succeeds in spite of the fact that those directories don't actually exist on my machine.
