Comment (by kencu):

 ChatGPT:

 The error message you're encountering indicates that you're trying to
 access the data member of a std::vector<double>, but the data member does
 not exist for std::vector prior to C++11. The data member function was
 introduced in C++11.

 If you're using a compiler that supports C++11 or later standards, you can
 fix this error by ensuring that your compiler is set to use the correct
 language standard.

 so if we set this in the portfile somewhere, somehow, and make sure it
 takes effect:

 {{{
 compiler.cxx_standard 2011
 }}}

 we should be good to go
