When installing Xcode 3.0 on Leopard, by default Unix developer support is disabled. That is, by default the command line tools (gcc, ld, etc.) are installed in /Developer without adding to the boot volume symlinks to the tools in /usr/bin or to the header files in /usr/include. Does MacPorts, including both the application itself as well as its individual ports, require those tools to be in /usr? Or, is it just necessary for the tools to be visible in one's PATH? The issue would arise if, for example, makefiles used hardcoded paths like /usr/bin/gcc or #include directives used paths like /usr/include/ stdio.h. Do port maintainers attempt to remove such fully qualified filenames when working on a port? I'd prefer not to have the development tools in /usr just because I just like keeping the root file system as clean as possible. But if MacPorts needs it, I'll break the rule. Thanks in advance, J.D.
