The --std option needs to be added to CPPFLAGS in order for this package to compile with GCC 5.4.0. The option can be set to c++11 or gnu++11. I was able to get the package to compile using c++11.

The error received without the option is:

This is actually the start of a cascade of several thousand errors from the package but adding "--std=c++11" to CPPFLAGS before running ./configure fixes it and the package will compile and install.

Thanks.
