It was a pain, but this ought to work:

# apt-get install kde-devel automake1.9
# tar -vjxf /home/priddle/Desktop/projectmanager-0.1.2-24.tar.bz2 -C /usr/src/
# cd /usr/src/projectmanager/
# ./configure --prefix=/usr
# make
# make install

I just did a clean install and I’m determined to keep it that way. So I removed these packages after:
