bash curl command not found on OS X. Where can I find it?

Question

I have no idea what I am getting myself into, I am very new to programming and trying to learn on my own. I am trying to install homebrew with ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go) and this the outcome is "-bash: curl: command not found"

I have been searching Google but can't seem to find anything to help me. when I type which curl it just goes to the next line of terminal as if I just opened terminal...
I have xcode installed with command line tools installed, and even downloaded reinstalled it in case something was wrong with it. Not that it matters but the reason I am attempting to install homebrew is it is needed for libsodium which is needed for dnscrypt.

When I type curl-config it gives me available values for OPTION include:

  --built-shared says 'yes' if libcurl was built shared   --ca        ca bundle install path   --cc        compiler   --cflags    pre-processor and compiler flags   --checkfor [version] check for (lib)curl of the specified version   --configure the arguments given to configure when building curl   --features  newline separated list of enabled features   --help      display this help and exit   --libs      library linking information   --prefix    curl install prefix   --protocols newline separated list of enabled protocols   --static-libs static libcurl library linking information   --version   output version information   --vernum    output the version information as a number (hexadecimal) 

Then I try any of of those like curl --version and it does the same curl command not found

As an alternative you can use wget:

ruby -e "$(wget -qO - 'https://raw.github.com/mxcl/homebrew/go')"
