Hi! I've just committed an update for png to 1.5.1beta1 (containing a security fix for 1.5.0, to which I originally wanted to update). This only concerns pkgsrc-current users, 2010Q4 is not affected. The shared library name changed, so I had to sweep pkgsrc and bump PKGREVISIONs. png-1.5 supposedly breaks nothing that compiled with 1.4 without warnings. Let me know if you find breakage anyway, I'll take a look at it. Thomas
