When I run the fpc 3.0.0 installer, I get a message indicating that my primary hard disk is not available because I don't have Xcode and the command-line tools installed. But I have both installed and up-to-date, so I have no idea what it's complaining about.
When I try to run "sudo xcode-select --install" even though the cli tools are already there, I get a message saying that the requested software is not available from the update server - which I'm told is a normal (if misleading) message when the software is already installed. Which I know it is because I do nothing *but* command-line development.
I'm on OS X 10.11.3, with XCode 7.3.1 installed via the Mac App Store.
Any suggestions welcome.
