Topic: ImageMagick7-devel requires libwebp7-devel, missing from CentOS6
I found that a similar problem was sorted out for CentOS 7, https://forum.remirepo.net/viewtopic.php?id=3818, but I'm pretty sure libwebp7(-devel) isn't available in any way for CentOS 6 yet, but now there's a dependency on libwebp7-devel in ImageMagick7-devel-7.0.8.41-1.el6.remi.x86_64. At least there isn't anything depending on libwebp7 outside of the -devel, so I just removed the ImageMagick7-devel for now. But it would be nice to have it back soon.
