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).

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:

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

/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.
----------------------------------------------------------------------
./install-sh -c -d '/usr/local/include/SDL2'
/usr/bin/install -c -m 644 SDL_ttf.h '/usr/local/include/SDL2'
./install-sh -c -d '/usr/local/lib/pkgconfig'
/usr/bin/install -c -m 644 SDL2_ttf.pc '/usr/local/lib/pkgconfig'
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
