[Xquartz-dev] question about libpng in recent X11 packages

I noticed that recent X11 development releases include both libpng12 and libpng14 in /usr/X11/lib. I think these are conflicting. I was having some difficulties compiling some open source apps, and in debugging, found that I had to completely prune out libpng12 from there. libpng14 is backward-compatible with 12, it is hard for me to understand why there is a reason for both to be present. On my system, the following changes improved compiler compatibility: cd /usr/X11/lib sudo rm libpng.3* libpng12* libpng.la sudo ln -s libpng14.la libpng.la Comments? Dave
