The CentOS6 rpms require the EPEL6 repository to be added to the yum 
configuration.

This is because, CentOS is a server OS, which (deliberately) does not 
supply many packages, one would need in a development environment.
You'll need to pull these from other sources. One possibile solution 
would be to statically link during building the toolchain rpms, another 
one is dynamically link against packages from 3rd party add-on repositories.

As static linkage is a short sighted and often inapplicable approach, I 
resorted to using the latter alternative and am using the latter 
approach - The packages missing in CentOS6 are pulled from EPEL6.

Yes. I don't know how these images were composed, but it actually means, 
these images were not set up correctly/properly.

;)

  As mentioned many times before, bootrapping has always required the 
rtems autotools being used. That said, it could be your autotool issue 
could be an issue with your user's $PATH.

Whether vendor-supplied versions of the autotools work, is mere random 
luck. The older a hosting OS is, the less likely it is, the vendor 
supplied versions work.

I'd guess so ;)
