Installing general package in octave has error

I have error in installing general package using the instruction.

pkg install -forge general

and get the message

octave:3> pkg install -forge general

I have no idea to solve this problem. My computer OS is Mac 10.9.3 Mavericks. Octave version is 3.8.0

Does anyone have idea?

I find the solution! Using this comment

xcode-select --install

and it's success!

I was having the same issue when trying to install the Octave Signal Package without success. The following finally appears to be working.

code-select --install from the Terminal window to install the command line tools
Install MacPorts for Mac. This is a standard installer that you can download from Macports.
sudo port install gcc48 --> This is a Fortran compiler, which is necessary for installing octave-general
sudo port install octave-general [NOTE: THIS TOOK A VERY LONG TIME, and I had to disable Spotlight indexing...Hours on a Macbook Pro]
sudo port install octave-control
sudo port install octave-signal

I found this theard looking how to install control pkg. I found solution on Arch Linux wiki:

Note: Some Octave's packages, like control, need the gcc-fortran ArchLinux's package in order to compile and install.

So you just need find fortan compiler for your distribution (or other operation system) and install it.
