When I tried to download and compile this package myself, I ran into a similar issue:

utils.cpp:69:14: error: use of undeclared identifier 'atof'; did you mean 'stof'?

alpha = atof(argv[++i]);

^{~ stof}

I don't know what's causing this. This seems to be related to a VNC bug that was just resolved.

When I added the following line to source code src/utils.cpp

#include <cstdlib>

I was able to compile the package on my own - without using macports.

Thanks.
