Emacs configure does not find giflib on Max OS X

Emacs configure does not find giflib on Max OS X

[Sam Steingold]

Hi

The current git tip of the emacs source tree does not find graphics libs
installed using `brew` (and never did, so this is not a regression):

    $ brew install jpeg giflib libpng libtiff
    Warning: jpeg-8d already installed
    Warning: giflib-4.1.6 already installed
    Warning: libpng-1.6.13 already installed
    Warning: libtiff-4.0.3 already installed
    $ ./configure --with-ns --with-png --with-jpeg --with-tiff --with-gif
    ...
      Does Emacs use -ljpeg?                                  no
      Does Emacs use -ltiff?                                  no
      Does Emacs use a gif library?                           no 
      Does Emacs use a png library?                           no 

What am I doing wrong?

thanks

Mixing NS and non-NS libs?  --with-ns does not use any of those graphics 
libraries.  It uses Gnustep/Cocoa graphics instead.

IOW, NS build can read graphics files without those libraries, right?
Thanks.

PS. I wish it were documented in "configure --help"
