You'll need to install Xcode (see the Mac FAQ).

It means you didn't install Xcode unix system tools. In that case you have to make sure they are on the PATH in the shell that you are using R CMD INSTALL on (again, see the FAQ)

BTW: is there any reason why you're not using the binaries? JavaGD is available as binary and PostgreSQL is not a dependency thereof ...
