 On Fedora you need qt-devel, marble-devel, libzip-devel.
 
+Building the Qt version under MacOSX
+------------------------------------
 
+You might have built MacPorts packages with +quartz dependencies to
+build the previous Subsurface/Gtk version.  Switch to the +x11
+dependencies and prepare your system for Subsurface/Qt by doing:
+
+sudo port uninstall gtk-osx-application subsurface libdivecomputer
+sudo port install cairo +x11 pango +x11 py27-pygtk +x11 gtk2 +x11
+sudo port install qt4-mac marble libzip libtool libusb
+
+Then build libdivecomputer and Subsurface as described below.
