help for first installation of rtems

[Matteo]

Hi 
I have intel centrino and linux ubuntu and I would like to install the RTEMS.
I download rtems-4.6.5.tar.bz2 and I unpack and uncompressed it in  
/myhome/rtems/rtems-src/
After I do    /myhome/rtems/rtems-b/../rtems-src/configure and all ok
and I read message to do make all to build to use the posix and I do it
 /myhome/rtems/rtems-b/make all and I had an error message like this ;

...
...
Making all in rtems
