good catch. I was only closing the terminal and then reopening it. So 
after logging out my path is /usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin.

so I reverted my path back to

PATH=${JAVA_HOME}/bin:$HOME/opt/hg:/sbin:$HOME/bin:$PATH

closed and reopend the terminal and now the path is

/home/gps/opt/jdk1.6.0_06/bin:/home/gps/opt/hg:/sbin:/home/gps/bin:/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin

which is correct. Not sure what was going on.

Thanks,
