Hi Dong,

  You will need liblwp, librvm and librpc2 to be able to compile coda-5.3.8.
They should be available at the same place where you got coda-5.3.8.

For completeness:  at ftp.coda.cs.cmu.edu:

   /pub/lwp/redhat-linux/SRPMS/lwp-1.4-1.src.rpm 
   /pub/rpc2/redhat-linux/SRPMS/rpc2-1.5-1.src.rpm 
   /pub/rvm/redhat-linux/SRPMS/rvm-1.1-1.src.rpm
