I started down the track of getting the latest KDE building with Qt/Mac. I ended up hitting a number of snags, so I'm pretty much stuck until someone more code-savvy than me looks at it (ie, Sam 😉
In the meantime I'm getting the rest of my patches and stuff sent upstream so we're ready. It won't be too long until KDE CVS builds out-of-the-box on Mac OS X (yay!).
As for Qt/Mac, I assure you that as soon as there's something to give you guys, I'll make a note of it here. Just hold your horses a little while longer unless you want to get in on the super-fun porting action... (no, no sarcasm there... <grin>)
