How can I find out if I have gcc installed on my machine?
I am trying to run CodeRunner, but it isn't responding. I know you have to have gcc installed in order for it to work properly. I do have Xcode 4.0.2 installed (from what I've read, if Xcode is installed then you already have gcc).
gcc at the Terminal prompt. If it says "command not found", you don't. Otherwise, you do.
$PATH it's not going to be useful, as most scripts that rely on it being "installed" will probably rely on it also being in $PATH and thus callable as gcc instead of /my/dumb/install/location/gcc
gcc -v to get the installed version number.

gcc under /usr/bin is optional in Xcode’s installer.
You could just try to see if a gcc executable is present. Try:
ls /usr/bin/gcc*
/usr/bin in your PATH, your Mac OS is likely to be broken.
.bash_profile for the particular user, the PATH could be messed up while the system is ok.

whereis/which can not find it
You can use "locate gcc" to find all filenames with gcc in them.
Try any terminal command, like:
$ gcc --help
If gcc isn't installed, you will often see a message with a "how to install it" note, complete with the package manager's command.
On Terminal type
gcc -v
You will get something like below
Using built-in specs.
......
gcc version 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.11.00)
This will show you version of GCC installed on your machine. If gcc is not installed then this command will not work as above
