Yes, indeed the new libpng-1.4 is breaking a lot of packages (think i read 
sth. about relation to not using --as-needed or so on some gentoo-related 
blogs ).
After fixing the qt-3 ebuild it still broke bluefish and some others....

For the time being i would suggest masking libpng-1.4... until this is 
resolved.
