configure.cpp should be populated for most compilers, but MacPorts does not set
the CPP environment variable for you; doing so caused problems for more ports
than it solved.
If you have a port that needs CPP set, set it yourself, as in:
configure.env CPP=${configure.cpp}
But I do see that configure.cpp is empty when the compiler is clang. Typically,
when $(CPP) is empty, software will use "$(CC) -E". So you could try setting it
that way.
