I've had problems like this and they were due to differences in
environment variables.  When you run it in a shell, is that a shell
inside Emacs?  Even so, if you are setting TeX related environment
variables like TEXINPUTS in your .bashrc, then they won't get picked
up by Emacs on OS X, _unless_ you started Emacs from a shell.  The way
to set environment variables in OS X is in ~/.MacOSX/environment.plist
though of course you can also set them in your .emacs.  

FWIW I keep environment.plist updated automatically using a method
similar to the one found here:
