How do I tell Homebrew that I indeed do satisfy a sdl_ttf library dependency for installing pygame?

Question

I am new to brew and have been using it to great effect until now. I am trying to install pygame, and it is not letting me get past one of the dependencies, sdl_ttf . I am running OS X 10.9 (Mavericks). The bottom line is that I have now downloaded and successfully installed the package myself but brew still keeps asking for it and failing.

From my perspective I have installed the dependency, so brew should let me proceed in the first place. One option is to "convince" brew that I have the dependency. Another option is to help brew install it again so it is happy. I don't know too much about make, but brew seems to be failing in the libtool: link: clang section. If I could override -lpng15 to be -lpng16 my hunch is that it will proceed (but I could be wrong).

Attempt to install pygame (and sdl_ttf dependency): 

brew install pygame

ld: library not found for -lpng15
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [libSDL_ttf.la] Error 1

The issue with lpng15 stuck in my memory because I had a previous install issue with a missing library called libpng15 versus libpng16. I think my hunch was right -- when I downloaded the SDL2_ttf-2.0.12 source and ran ./configure, make, make install, it used lpng16, not lpng15 as above:

look in that last part - it used lpng16, probably based on the config that ran:

libtool: link: gcc -g -O2 -I/opt/local/include/freetype2 -I/usr/local/include/SDL2 -D_THREAD_SAFE -DHAVE_OPENGL -o .libs/glfont glfont.o -Wl,-framework -Wl,OpenGL ./.libs/libSDL2_ttf.dylib -L/opt/local/lib -L/usr/local/lib -lfreetype -lz -lbz2 -lpng16 -lSDL2

remember when brew ran this segment it tried to use lpng15 and couldn't find it: 

ld: library not found for -lpng15

the install in this case continues to go smoothly (but after brew still has no idea and wants the sdl_ttf dependency from the beginning of the post):

make install output: 

  make install
     ./install-sh -c -d '/usr/local/lib'
     /bin/sh ./libtool   --mode=install /usr/bin/install -c   libSDL2_ttf.la '/usr/local/lib'

    Libraries have been installed in:
       /usr/local/lib

    If you ever happen to want to link against installed libraries
    in a given directory, LIBDIR, you must either use libtool, and
    specify the full pathname of the library, or use the `-LLIBDIR'
    flag during linking and do at least one of the following:
       - add LIBDIR to the `DYLD_LIBRARY_PATH' environment variable
         during execution

    See any operating system documentation about shared libraries for
    more information, such as the ld(1) and ld.so(8) manual pages.

I think the problem is that you upgraded libpng since you installed freetype, so freetype-config --libs is giving a bad answer. brew update; brew upgrade; brew reinstall freetype brew update; brew upgrade; brew reinstall freetype should fix this "the right way."

It seems that libpng15 may have been replaced with libpng16 . What I would try is creating a symlink from libpng16 to libpng15 (It should be backwards compatible).

So assuming libpng is in /usr/local/lib 

#create a link so any requests for lpng15 use lpng16 instead
sudo ln -s /usr/local/lib/lpng16.so /usr/local/lib/lpng15.so

Make sure you verify this is the actual location of the library on your machine (I don't have an OS X box to test on)

EDIT Based on the output of your /usr/local/lib , try the following - it links any missing libpng15 files to use libpng16. 

sudo ln -s /usr/local/lib/libpng16.a /usr/local/lib/libpng15.a
sudo ln -s /usr/local/lib/libpng16.dylib /usr/local/lib/libpng15.dylib
