Qt has updated (several times, including bits where it didn't compile at all). Lukas has added several new pspcs just today. I've rebuild all the dependencies on my nv83 workstation and it seems to work -- except for ksmserver, which is worrying. The techbase page for KDE4-Solaris has been updated but could use some further attention. KDE4 compile status is back to "13 modules compile and mostly work".
