I had installed rmagick gem on ubuntu 7.10. I have also compiled  
imagemagick from sources becouse rmagick needs \> 6.3. version of  
imagemagick. Mine is now 6.3.9.

At the end everything went fine until I tried to run test program. I got  
this error.

/usr/lib/ruby/gems/1.8/gems/rmagick-2.2.2/lib/RMagick2.so:  
libMagickWand.so.1: cannot open shared object file: No such file or  
directory - /usr/lib/ruby/gems/1.8/gems/rmagick-2.2.2/lib/RMagick2.so

As I understand RMagick2.so is unable to load libMagickWand.so.1 which  
only points to libMagickWand.so. I have tried all kind of options  
including copying libMagickWand.so from /usr/local/lib to  
/usr/lib/ruby/gems/1.8/gems/rmagick-2.2.2/lib. But nothing helps.

What have I done wrong?

Ubuntu doesn’t look in the gems path for libMagickWand.so. It only looks  
in its own load path, so copying libMagickWand.so there won’t help. You  
have to tell Ubuntu where to search for libMagickWand.so. See if this  
tip helps: [http://rmagick.rubyforge.org/install-faq.html#loaderror](http://rmagick.rubyforge.org/install-faq.html#loaderror).

If that doesn’t work, post a question on the RMagick Help forum on  
RubyForge and I’ll follow up when I get home.

Yep. It helps. Thanks a lot.
