An alternative would be to just provide a recent libpng12.so.0 with the binaries. You might have to use either gcc's -rpath option or LD_LIBRARY_PATH to make sublime_text pick up the new version. This should be compliant with LGPL, and since libpng does not have many dependencies, should also work on older systems.
