PROBLEM SOLVED: error in starting ddd with gdb for Fortran code

[mccomb]

I solved my own problem. When I downloaded gcc, I only installed the binary 
code. Since the library /libf2c/libF77 was not resident in /usr/local, gdb 
could 
not find the necessary c-code translations to run the debugger properly. 
Downloading the source code for gcc then compiling and installing it using my 
existing binary version of gcc did the trick (although it did seem somewhat 
incestuous!)
