I’ve installed the most recent qt on Snow Leopard and it seems to reference /usr/X11/lib/libpng15.15.dylib which I don’t have. Qt progams I compiled with that version will crash:

dyld: Library not loaded: /usr/X11/lib/libpng15.15.dylib
  Referenced from: /usr/local/Cellar/qt/4.7.3/lib/QtGui.framework/Versions/4/QtGui
  Reason: image not found
Trace/BPT trap

Seems like Qt should be linking to libpng.dylib and not to the specific versioned dylib.

Can be corrected with an install_name_tool line @MikeMcQuaid. Though annoying to have to do it.

If it's not binary compatible (then I'm miffed with the libpng guys) and we'll just have to force source compiles on < 10.7.

I’ve tried linking libpng.dylib to libpng15.15.dylib. While it did run, it complained a lot about png.h being incompatible with png.c. (Don’t have the Mac with me right now, so I can’t give the exact information.)

A faster solution for me (instead of compiling Qt myself) was to download the newest source of libpng and then put the self-compiled libpng15.15.dylib into /usr/X11/lib (no headers). Not sure, if this will eventually break my system or something.

Build from source (for now) unless on Lion.

Longer-term we'll try and use install_name_tool to fix Lion
bottles so they run fine on 10.5 and/or 10.6.

Closes Homebrew#6699.
