Can't install 'rmagick' Ruby gem...

Hi all,
Has anyone been able to successfully install rmagick on slackware 13.1? On both my systems (one multilib and one 32-bit), it complains about having a 'partial' ImageMagick install!

Code:

$ sudo gem install rmagick

Building native extensions.  This could take a while...

ERROR:  Error installing rmagick:

        ERROR: Failed to build gem native extension.



/usr/bin/ruby extconf.rb install rmagick

checking for Ruby version >= 1.8.5... yes

checking for gcc... yes

checking for Magick-config... yes



Warning: Found a partial ImageMagick installation. Your operating system likely has some built-in ImageMagick libraries but not all of ImageMagick. This will most likely cause problems at both compile and runtime.

Found partial installation at: /usr

Could not create Makefile due to some reason, probably lack of

necessary libraries and/or headers.  Check the mkmf.log file for more

Which development tools? AFAIK, Slackware has full installs of Ruby and Imagemagick. There are no 'dev' versions of packages, everything is included from the get-go. So what am I missing?

I found this on the slackbuilds.org mail list:

https://rcpt.yousendit.com/101792090...28116c1b86c27d

I hope it works

Doesn't seem to :(

Code:

$ pdfbeads

I do not think this is a Slackware problem; am opening an issue with RMagick on github... (yes I tried the git version too.. same failure to compile).

EDIT: .tgz provided in that zip (2.5.1) is too old for 13.1's version of ImageMagick; using the SlackBuild with 2.13.1 (latest, supposedly compatible) fails with same error...
