Unfortunately, didn't work correctly. Running SAGE_INSTALL_GCC=yes make
seems to do something wrong to gmp. e.g., while building GMP-ECM... checking if gmp.h version and libgmp version are the same... (6.1.0/5.1.3) no configure: error: 'gmp.h' and 'libgmp' have different versions, you have to reinstall GMP properly. Error configuring GMP-ECM. Is it possible that some environment variable I've set has messed something up? Also, I ran make distclean instead of really starting from scratch. Is that relevant?
