Here's how I got 0.10.2 to compile.
Edit kopete-0.10.1/doc/Makefile and find the line that starts TOPSUBDIRS=
You'll see alot of words, doc kopete po, etc. Delete fr, de, es, leaving only doc, kopete and po. There are documentation for other languages, french, german, spanish, etc, which you probably don't care about. NOTE TO THE KDE TEAM: If you detected an English system, (or Spanish), why bother including other languages in the documetation compilation???
Edit the file kopete-0.10.1/kopete/kopete/chatwindow/kopetechatwindow.cpp, and on line 563 type // before the 'm_tabBar->setAuto.. line.
In kopete/protocols/groupswise/ui/gwcontactpropswidget.cpp comment line 93, setShadeSortColumn.
Run make again, and everything should install.
