imagick compilation

Hi, I'm having problems installing the imagick module. I'm using PHP 4.3.1, imagick 0.9.5 and ImageMagick 5.4.7. Magick-config is in /usr/bin, and ImageMagick is in /usr/lib/ImageMagick. I put imagick into php-4.3.1/ext, run phpize, cd ../../, ./buildconf, and ./configure --with-apxs=/usr/sbin/apxs --with-bz2 --with-gettext --with-pgsql --with-gd --with-freetype-dir --enable-mbstring --enable-mbregex --with-zlib-dir --with-imagick=/usr/lib/ImageMagick I also tried with the Image Magick path (i.e., just --with-imagick). This is the error I get when compiling: /home/jonas/hent/programmeringssprog/php-4.3.1/ext/imagick/imagick.c: In function `zm_startup_imagick': /home/jonas/hent/programmeringssprog/php-4.3.1/ext/imagick/imagick.c:625: `RLECompression' undeclared (first use in this function) /home/jonas/hent/programmeringssprog/php-4.3.1/ext/imagick/imagick.c:625: (Each undeclared identifier is reported only once /home/jonas/hent/programmeringssprog/php-4.3.1/ext/imagick/imagick.c:625: for each function it appears in.) make: *** [ext/imagick/imagick.lo] Error 1
