Version:            (using KDE KDE 3.2.2)
Installed from:    Compiled From Sources

There is what I do:
wget http://developer.kde.org/build/konstruct/stable/konstruct-stable.tar.bz2
tar -xjvf konstruct-stable.tar.bz2
cd konstruct/
vi gar.conf.mk
# enlever le signe dièse (#) devant la ligne HAVE_QT_3_2_INSTALLED
# [ESC]:wq
cd meta/kde
make install

There what i've got:
 ==> Running checksum on kdesu.diff
df51c6413f72ad8766f990d98b11d6cd  download/kdesu.diff
download/kdesu.diff: FAILED

it's from ftp://ftp.oregonstate.edu/pub/kde/stable/3.2.2/src/kdelibs-3.2.2.tar.bz2 I think

Expected result:
have a beautiful kde3.2.2 installed after two/three days (i'm on a 300mhz) of compilation ;-)
