Try these. I faced the same issue and it worked for me. First install libxml2 and then run bundler again.

 brew install libxml2

Update:

I am hoping that you have homebrew installed. If you don't have homebrew then I will suggest you to install homebrew and then install libxml2 and then bundler. Don't use mac ports in case you don't have homebrew.

Update:

It's not an issue of command line tools. It's failing at libxml. Try to read the error and you will see

    checking for libxml/parser.h... *** extconf.rb failed ***

And that's the issue

After short research I find out what problem can be simply solved by creating symbolic link

sudo ln -s /usr/bin/gcc /usr/bin/gcc-4.2

works for me hope for you too

I think this is the most important bit of the error message:

warning: Insecure world writable dir /usr/local in PATH, mode 040777

Some part of the build process is whining that that directory has permissions such that anyone can write to it. You could try to hunt it down - or you could fix it.
