Hi, David,
Thank you for the prompt reply.
I merely followed the procedure in the INSTALL file.
I have no idea how it reached fantasian.o program.
Another problem I had on other redhat 6.2 bug: 
After the "d. cd $AMBERHOME/src/roar-2.0 " step,
I receive the following error message 
associated with "-n32" as below, 
"
f77: unrecognized option `-n32'
f77 -n32 -O3 -c lbfgs.F
f77: unrecognized option `-n32'     
....
"
Please help.
Thank you.
Regards,
Margaret
