The RPM specs being used can be found 
* in the corresponding *src.rpms.
* in the scripts/autotools directory of RTEMS source tree.

The RTEMS autotools are the officially stable, vanilla FSF versions
built from original tarballs without any patches or hacks

-> If your vendor ships autoconf-2.57 and automake-1.7.2 (I am not aware
of any vendor currently shipping them), there should not be any need to
install the RTEMS autotools.

To install them manually, the only prerequisite is to build autoconf and
automake with the same prefix and to make sure that these tools can be
found in $PATH, when installing them and when working with RTEMS.

The basic installation instructions is this:

export PATH=<myprefix>/bin:$PATH

cd <somewhere>
tar xjvf autoconf-2.57.tar.bz2
cd autoconf-2.57
./configure --prefix=<myprefix>
make install

cd <somewhere>
tar xjvf automake-1.7.2.tar.bz2
cd automake-1.7.2
./configure --prefix=<myprefix>
make install

We are using --prefix=/opt/rtems, but essentially any other arbitrary
prefix should do. However, using --prefix=/usr or --prefix=/usr/local
will override your vendor autotools and might not be what you actually

=> I recommend to install copies of autoconf and automake into the same
prefix as you installed your cross-toolchain and to prepend the path to
these tools to your $PATH if working on RTEMS:
