Is there any way to get the last several subdirectories of `pwd`?

I need to modify the .profile of an account, and I have this line in the .profile:
PS1=`hostname`':$LOGNAME:$PWD>'

But my boss want me to get only the last 3 levels of the subdirectory if `pwd` returns a long path. For example, if `pwd` returns /appl/oracle/instance001/d01/oracle/001appl/admin,

then he want only oracle/001appl/admin displayed. Could anybody help me? I have tried to use 'cut -d/ -f ...', but it does not work for me.


Thanks in advance.
