try building the ruby source this way so it builds and installs under
your home folder, you can later just delete this folder without worry

cd ~
mkdir -p ruby/local/

now cd into the source folder where you extracted the ruby source

NOTE: the use of tilda ~ in the path below, you want to install it
under your home folder ~/ruby/local/

./configure --prefix=~/ruby/local
make
make test
make install

export $PATH=~/ruby/local:$PATH

now test if you can run ruby with:
ruby -v

the export command will only be good for the current session, if you
want to make it permanent, save it to you bash start up file

nano ~/.bashrc

add the line at the bottom of your file

$PATH=~/ruby/local:$PATH

save and exit the file

btw, i am assuming you're using the bash shell. if you still don't
know what to do ask your sysadmin for help at school
