Brief note: Installing xemacs-21.1.13 with libpng-1.2.4 rather than the earlier version 1.0.6 of libpng works if one supplies a soft link: /usr/local/lib/libpng.so.2 -> libpng12.so.0.1.2.4 At least I needed to supply the link; otherwise I got: meitner% xemacs ld.so.1: xemacs: fatal: libpng.so.2: open failed: No such file or directory Killed
