Comment (by mbrethen):

 Yes, CalculiX is composed of two independent packages: ccx and cgx. #57715
 installs ccx, the main tool for doing finite element analysis (FEA). It
 depends on fortran and, according to the documentation, needs be built
 with GCC. #57763 installs the pre/post-processor cgx. It uses OpenGL and
 the C++libraries it depends on are built with native clang. Building it
 with GCC could cause C++ library conflicts, I'm told.

 I made them independent ports to better focus on the specific requirements
 of each tool and avoid compiler-related conflicts. Hope this helps.
