# Well, glad I got rid of the above, but <someone> upstream still does not
# grok shared libraries on Linux it seems -- libpng-1.4.0 caused all the
# newly compiled binaries to want libpng.so.14, and now libpng-1.4.1
# wants to change that to libpng14.so.14. Searching online finds that
# we are not the only ones with binaries that want libpng.so.14, so we
# are forced to provide a compatibility symlink again... :-/
