 GENERAL BUILD STEPS
 ^^^^^^^^^^^^^^^^^^^
 
-1. CD to the correct directory.
+1. Configure your host machine.  You host PC should have a relatively complete
+   C development environment.  I don't have a full list of the package requirements.
+   The later tool chains also require GMP and MPRF development packages or the
+   build will fail with errors like:
+
+    "configure: error: Building GCC requires GMP 4.1+ and MPFR 2.3.0+. ...
+     Copies of these libraries' source code 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 and/or MPFR 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."
+
+   You should try your package manager for whatever Linux version you are using
+   first.  The header files are normally included in versions of the packages that
+   have "-devel" in the package name.
+
+2. CD to the correct directory.
 
    Change to the directory just above the NuttX installation.  If <nuttx-dir> is
    where NuttX is installed, then cd to <nuttx-dir>/..
