I don't understand this: the message you show only appears when  
building the text mode IDE, and the text mode IDE is not built for Mac  
OS X (unless you manually go into the IDE directory and execute make  

The error message about "no debugger support" means that there will be  
no internal debugger in the IDE. It does not mean that the units or  
the compiler do not contain debug information.

You do not need libgdb.a (unless you want to build the text mode IDE  
with internal debugger support on Mac OS X, but then you are on your  
own -- this is not tested/supported/planned).
