Jim:
The "Development Tools" group I believe has the compiler and other items needed to compile programs on the machine. You can either useyum groupinstall "Development Tools" or select the development group from the add/remove programs.
OK - looks like I installed the necessary bits (./configure works). However, there was one 'issue' - ./configure: line 1652: dbl: command not found Is this a problem? It just occurred to me that I might have to be in SU mode; is that correct?
