rmagick problem on Ubuntu

[Damjan Rems]

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.

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.
