png-1.4.1
qt-3.3.8_11 (upgrading to qt-3.3.8_12)
>Description:
Build of x11-toolkits/qt33 fails due to the changed struct png_info
in libpng-1.4:
kernel/qpngio.cpp:162: error: 'struct png_info_struct' has no member named 'trans_values'
>How-To-Repeat:
run portupgrade
>Fix:
Add x11-toolkits/qt33/files/patch-src-kernel-qpngio.cpp
