ja kirjutame

autoconf
 ./configure --with-layout=freebsd
make testdeps

arvatavasti teatatakse puuduvast tarkusest niisiis kirjutame

make fixdeps
make install

ImageMagick ei installita vaid ainult cpanel asjad make fixdeps'iga nii peame

cd /usr/ports/graphics/ImageMagick
make install clean

ja rrdtool graafikuteks

cd /usr/ports/net/rrdtool
make install clean
