Comment(by Pavel.Vondricka@…):

 Same result. :-(

 BTW, I have no quadcore, just dualcore.

 Could the problem be, that I am doing an "upgrade" and not "install"? I
 have version 4.4.3 installed, but cannot upgrade since that time. I have
 surely installed lot of things inbetween (including iPhone SDK or other
 updates to Xcode) and there are different versions of libpng lying around
 in the system (nothing suspicios in /usr/lib though). However, it seems it
 is linking to the right one...?
