I'm having trouble installing the Python Pandas library on my Mac OSX computer.

I type the following in Terminal:

```
$ sudo easy_install pandas

```

But then I get the following:

```

```

I do have Xcode and gcc installed, however, gcc is only found when I type:

```
$ gcc
-bash: gcc: command not found

$ gcc-4.2
i686-apple-darwin11-gcc-4.2.1: no input files

```

What should I do?
