Hi all !

I just installed Mac OS X 10.5.1 on my Intel MacBook Pro. Since I have my
personal packages that I build and modify every so often I also installed
Xcode 3. My packages contain either some C code, some Fortran code or both.

However, I can not build a binary of my package, which I know to be
error-free since they were running without any bugs when I was running Tiger
(Mac OS 10.4.11).

The message that is sent to me when I launch the command "R CMD build
--binary AEM" (AEM being the name of my package) in the terminal is:


macintosh:AEM Package ti-guiblanc$ R CMD build --binary AEM

My knowledge of the UNIX code and the terminal is limited, so please be
gentle !

Thanks in advance for any help.

Have a nice day !
