Issues with configuring BSP with waf

Hello,
I did follow the instructions in
https://docs.rtems.org/branches/master/user/start/app.html, added init.c,
modified hello.c and added wscript. I ran the command:
./waf configure --rtems=$HOME/quick-start/rtems/6 --rtems-bsp=sparc/erc32
But still ended with same error like before. I don't know what I am
missing. I don't think I have skipped any step.
Still got this error:
Setting top to                           :
/home/idadel/quick-start/app/hello
Setting out to                           :
/home/idadel/quick-start/app/hello/build
RTEMS path is not valid, "/home/idadel/quick-start/rtems/6/share/rtems5"
not found.
(complete log in /home/idadel/quick-start/app/hello/build/config.log)
