i already tried this why and where stands /home in $PATH ?

This has nothing to do with $PATH (well, as far as I know :p). It means that your home directory (/home, in this case) has too many permissions. As far as I can see, it's set to 777, which means that just anybody can read, write and execute files in your home directory, which obviously is unsafe.

You should change your directory's rights as following:

chmod 755 /home

Do not use the -R flag (which stands for recursive). Files should only have 644, not 755.

BTW, you don't use rvm to install rails with.

You do something like: rvm install 1.9.2 && rvm --create use 1.9.2@foo && gem install rails
