Problem solved :)

SuperTux had the same problem.
$ supertux 
[...]
Error: Can't load
/usr/bin/../share/supertux/images/status/letters-black.png
[...]

So, the problem was not on Pingus but on SDL_image.

I have written a minimal code using the SDL_image library to be sure.
And I got this error:
$ ./main.out 
IMG_Init: Failed loading png_set_longjmp_fn: /usr/lib/libpng.so.3: undefined 
symbol: _png_set_longjmp_fn

So, the problem is that SDL_image is using my libpng shared library that 
doesn't contain the required symbol.

I have recompiled SDL_image using these options:
--disable--jpg-shared --disable-png-shared --disable-tif-shared 
--disable-webp-shared

And now it works :)
