I'm trying to install a program from source code.  In running "configure", 
I get error messages about confdefs.h   I assume this is because there is 
no such file in my system.  Anybody know what package to install to get 
this file?  Mandrake 8.0  This kind of problem always happens to me.  Is 
there any easy way to locate these kinds of required files without always 
posting?
