v9.0 systemd - Chptr 6.21: GCC build - Building GCC requires GMP 4.2+, MPFR 2.4.0+ and MPC 0.8.0+

Here is the complete error:

Quote:

configure: error: Building GCC requires GMP 4.2+, MPFR 2.4.0+ and MPC 0.8.0+. Try the --with-gmp, --with-mpfr and/or --with-mpc options to specify their locations. Source code for these libraries can be found at their respective hosting sites as well as at ftp://gcc.gnu.org/pub/gcc/infrastructure/. See also http://gcc.gnu.org/install/prerequisites.html for additional info. If you obtained GMP, MPFR and/or MPC from a vendor distribution package, make sure that you have installed both the libraries and the header files. They may be located in separate packages.

I went back over those three packages again just in case I made an error. Even the checks all came out all okay.

Any ideas on what I may have missed to cause this?

Thanks!
