- switch COMPILER to ports-gcc only, due to limitations in the build system, MODULES=fortran requires ports-gcc anyway. If problems with C++ ever show up, we might make a version with fortran disabled and base-clang only. Compiling mpi applications with base-clang is still possible. - adjust SHARED_LIBS accordingly, add @so lib markers while there - add a simple README with example code joint effort with j@bitminer.ca
