I see the problem. Originally, Sage (or you) decided to install the GCC
package within Sage. As a consequence, MPIR was built without the C++
interface. From the MPIR log:
Building a reduced version of MPIR to bootstrap GCC.
MPIR will later get rebuilt (with the C++ interface and static libraries
enabled) using the new compiler.
Then MPFR failed, causing the build to abort. Then you messed with
CFLAGS (and maybe compiler versions?) and rebuilt Sage but this time
*without* installing GCC. This left the "partial" MPIR build in place.
Rebuilding MPIR should fix your problem.
Oh. That's nice.
Indeed, the build had failed once with it trying to install gcc. While
compiling or installing gcc it complained that some headers were missing.
It turned out that the reason why it was trying to install gcc was
because I didn't have gfortran in my system. So, I installed gfortran
and restarted the build of Sage.
I already started another build of Sage to check if it works this time
round. Hopefully it should turn out fine this time.
