Issues with configuring BSP with waf

[Ida Delphine]

Hello,
Please I need some help. Following the GSoC getting started guide(
https://docs.rtems.org/branches/master/user/start/gsoc.html),everything
went well to the point I had to do an offline download. I used this command
../source-builder/sb-set-builder --source-only-download 5/rtems-sparc
Seems like there was a mismatch. I got this error:
b-set-builder --source-only-download 5/rtems-sparc
RTEMS Source Builder - Set Builder, 6 (5e449fb5c2cb)
Build Set: 5/rtems-sparc
error: no build set file found: 5/rtems-sparc.bset
Build Set: Time 0:00:00.000205
Build FAILED
I then replaced 5/rtems in the command with 6/rtems and everything worked.
I was able to install the suite, build the board support package, and test
my BSP though along the way I had to replace "5" with "6" in certain
commands. Everything went well until I wanted to prove I can work on RTEMS.
I followed the instructions to create my hello application and added the
necessary .c files. The problem was when I tried configuring this
application using waf with the command:

./waf configure --rtems=$HOME/quick-start/rtems/5 --rtems-bsp=sparc/erc32

I 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/5/share/rtems5"
not found.
(complete log in /home/idadel/quick-start/app/hello/build/config.log)
I thought I showld startover but and work with rtems.git/5 instead of
rtems.git/master. Same with rsb. So I got the sources and did a "git
checkout"  from the master to the "5" branch. Everything went well with me
not not having to change any "5" to "6" in some commands. I didn't make it
as far as testing my BSP. I had issues with configuring my BSP with the
command:

./waf configure --rtems=$HOME/quick-start/rtems/5 --rtems-bsp=sparc/erc32

I got this:
bash: ./waf: No such file or directory
I'm confused and don't know what I missed or where I went wrong.

Ida.
