Wrong conclusion about gcc/make being 'apparently unavailable yet in chroot environment'. Further investigation found that, during a ./configure test (before 'make'), 'gcc' failed to create executables (for a small 'conftest.c'), with a message of "collect2: cannot find 'ld' ". However, 'binutils' was among the packages that had been installed prior to the %post section, and the directory /usr/bin (where ld lives) is found in PATH by ./configure. Also, in the system booted from the dvd image, the ./configure script runs successfully, and ld is where it should be. Google search so far hasn't turn up anything relevant. Suggestions and help are appreciated. Thanks
