Hello Railslist,

I’m trying to get Gruff running on OSX Tiger (intel) with edge Rails.  
I’ve installed ImageMagick, Rmagick, FreeType and all their  
dependencies, or so I believe. (I’ve compiled them from source mostly,  
following a recent tutorial for Rails and ImageMagick on Intel Macs)

While following the sample on the Gruff downloadpage (the one with the  
fruit), Rails throws a RuntimeError: “Can’t measure text. Are the  
fonts installed? Is the FreeType library installed?”

What do I need to do to fix this error?  
Thanks in advance!

By the way, the tutorial I mentioned is:

But in [http://topfunky.net/svn/plugins/gruff/lib/gruff/base.rb](http://topfunky.net/svn/plugins/gruff/lib/gruff/base.rb), I read  
the following:

# RMagick must be built with the Freetype libraries for this to work

properly.

In this other tutorial  
([http://rmagick.rubyforge.org/install-osx.html](http://rmagick.rubyforge.org/install-osx.html)), the DarwinPorts  
FreeType library is preferred over the X11 version, could this be the  
cause of my error?

Thanks…

ok, the solution is to install GhostScript  
(sudo port install ghostscript)
