Summary has it all. The package has no dependency information. It's a bit of a grey area on this one I think, but I'll explain. Package is pretty much useless without gcc-objc (at least how it is used in Arch PKGBUILDs that I've seen), but it is only a runtime dependency by definition. If it were mine, I think make and sh in depends, and csh, gcc-objc, and java (and this only if it can use javac as opposed to the now deprecated gcj/classpath) in optdepends. Do what you think is best, but at very least, some provider of /bin/sh and make is a hard dependency, and gcc-objc and csh in optdepends.
