Comment(by Pavel.Vondricka@…):

 BTW, I found libpng 1.4 in Qt4.7 beta (sources, at least), which I had
 installed (binary) in the system. (Another bug/ticket with the same
 unresolved symbol was apparently caused by the presence of libpng 1.4 in
 the system.)  I noticed some more mess when compiling things with qmake
 (like meaningless linking paths to /tmp/qt-stuff/...). I uninstalled the
 whole Qt4.7beta (hopefully correctly?), rebuilt qt4-mac and all
 dependants, but still it doesn't work... :-( Any idea if the problem could
 be related to this?

 (I also cannot compile the latest revision of qca-ossl, but that seems to
 be something more trivial... I'll create a new ticket, if the things
 really are not related/caused of some common mess in my system.)
