Good, I am using a separate user too. And Kubuntu's kde4 files are all
in /usr/lib/kde4/, so I hope this doesnot screw up my KDE3!

ok "moc-qt4 -v" shows
Qt Meta Object Compiler version 59 (Qt 4.3.2)

I think that is fine! Let me know if it is not..

$ cmake --version
cmake version 2.4-patch 7

so that is good.

Ah, I was doing it one level of directory deeper. Now it seems to work
but with the following output (and Error in the end:)

====================

On my machine, /usr/local/lib/R/site-library exists:
$ ls -l /usr/local/lib/R/site-library
-rw-r--r--  1 root root  608 2007-10-17 23:40 R.css
drwxr-xr-x 10 root root 4096 2007-10-17 23:44 rkward

/usr/lib/R/library contains all the usual libraries (with R.css)....
and /usr/lib/R/site-library is empty (exists though, but no R.css)...

I have R 2.5.1 though... For KDE3 compilation I had to use
CC=/usr/bin/gcc-4.2 and CXX=/usr/bin/g++-4.2 before ./configure. What
are the relevant options here?
