configure error while building RTEMS 4.5.0 on linux host

[anand v]

hi all

  I want to install RTEMS 4.5.0 on my linux PC.

For this I downloaded the RTEMS tarball from the
gaisler website and as per the instructions given in
the
"README.configure" text file..i attempted to build it
from the build directory...the configure process
stopped and returned to the shell prompt after
printing 100's of lines of some information ....the
last 2 lines pointed to some error...

**************************************************

Sequence:
[xxx at yyy build]$
[xxx at yyy build]$
[xxx at yyy build]$ configure
--enable-rtems="sparc-rtems"
                
--------------------------------------   
                 checking for------ 
                 checking for-------
                 ---------------------------- 
                 creating Makefile
                 configuring in ./c 
                 checking 
                   ......so on...

   finally the last 2 lines are:

checking for             
make/custom/sparc-rtems.cfg...configure:error:no
configure:error:/home/anand/tsim-eval/rtems/src/rtems-4.5.0-jg5/c/configure
