2015-11-27 Resolved "cannot build python-module libsass in [gcc 4.6 < ] environment, e.g. CentOS 6.5" Python $ pip install sass # not "libsass". it's another module This module uses a C++ Library "Libsass" Older Version. This doesn't have dependencies related to gcc 4.6.In the first place, I had tried to do "cross compile" Libsass. However I gave up this because it would cost a lot of hours.
