CalculiX is using libstdc++ (this installation is configured to use libc++)

[Mark Brethen]

I tried setting CFLAGS in he pre-build before, which negates the includes in the patch, and the build fails.

:info:build Executing:  cd "/opt/local/var/macports/build/_Users_marbre_ports_cad_CalculiX/CalculiX/work/CalculiX/cgx_2.18/src" && /usr/bin/make -j4 -w CXX=/usr/bin/clang++ CC=/usr/bin/clang CFLAGS="-Os -arch x86_64" LDFLAGS="-L/opt/local/lib -Wl,-headerpad_max_install_names -arch x86_64" 

:info:build In file included from adjustMidsideNode.c:31:
:info:build In file included from ./cgx.h:25:
:info:build ./extUtil.h:40:12: fatal error: 'GL/glut_cgx.h' file not found
:info:build   #include <GL/glut_cgx.h>
:info:build            ^~~~~~~~~~~~~~~

Either I add those to the patch or put everything in the pre-build.
