Error installing rmagick on Debian Sid

Question

I had to switch ruby version to 2.0.0-p353. I use rbenv and installed the p353 normally (rbenv install ).

For some reason rmagick failed to install on this ruby version. Full error here:

Fetching: rmagick-2.13.2.gem (100%)

ERROR:  Error installing rmagick:

Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers.  Check the mkmf.log file for more details.  You may
need configuration options.

Provided configuration options:
    --with-opt-dir
    --without-opt-dir
    --with-opt-include
    --without-opt-include=${opt-dir}/include
    --with-opt-lib

    --without-make-prog

Gem files will remain installed in /home/dot/.rbenv/versions/2.0.0-p353/lib/ruby/gems/2.0.0/gems/rmagick-2.13.2 for inspection.

I have all headers and -dev packages installed on my system since rmagick is installed in 2.0.0-p481.

$ rbenv version && gem list | grep rmagick
2.0.0-p481 (set by /home/dot/.rbenv/version)
rmagick (2.13.2)

.

apt install imagemagick libmagickwand-dev
imagemagick is already the newest version.
libmagickwand-dev is already the newest version.

Here is a fresh installation: http://paste.debian.net/hidden/102606b7/

Any ideas?

On Ubuntu:

▷ dpkg --search Magick-config
libmagickcore-dev: /usr/share/man/man1/Magick-config.1.gz
libmagickcore-dev: /usr/bin/Magick-config

That apparently means that you probably need to

▷ sudo apt-get install libmagickcore-dev

Hope it helps.
