 I used gcc-3.2.2.  I think gcc-3.2.1 works fine as well.
I downloaded  RTEMS4.6.0  from ftp://ftp.rtems.com/pub/rtems/4.6.0/
One should reference  Eric Norum's writeup :
http://www.aps.anl.gov/epics/base/RTEMS/tutorial/
in building the  GCC tool-chains and RTEMS and in learning
EPICS-RTEMS.

One example I have in building RTEMS is :

mkdir build
cd build
../rtems-4.6.0/configure -target=ppc-rtems -prefix=/opt/rtems3 --enable-cxx --enable-rdbg
--disable-tests --enable-maintainer-mode --enable-networking --enable-posix --enable-itron
gmake RTEMS_BSP=mvme2307
gmake RTEMS_BSP=mvme2307 install

Another option is to download the  prebuilt binary  files from
http://www.rtems.com/.....   instead of building it
yourself, which I never tried.

Cheers,
Kate
