`USE="perl" emerge media-gfx/imagemagick` appears to make the perl wrapper library link to the old version of libMagick. I had ImageMagick 6.2.5.5 installed, and upgraded to 6.2.8.0. $ ls -1 /usr/lib/libMagick.so* /usr/lib/libMagick.so /usr/lib/libMagick.so.10 /usr/lib/libMagick.so.10.0.3 $ ldd /usr/lib/perl5/vendor_perl/5.8.8/i686-linux/auto/Image/Magick/Magick.so ... libMagick.so.9 => not found ... Emerging once more will fix the linking, but a package shouldn't have to be emerged twice in order for it to install properly.
