I tried installing RMagick-1.9.1-IM-6.2.3-win32 gem on WinXp, running  
Ruby  
1.8.2, build 15 (12-25-2005).

I downloaded and installed the Win32 build of Rmagic as per the  
instructions:

1. Unpack the zip
2. gem install RMagick-1.9.1-IM-6.2.3-win32 gem
3. ruby postinstall.rb

The gem install tells me it successfully installed the gem. Postinstall  
throws a ton of warnings ala “Warning: Ignored file  
c:/windows/fonts/AcadEref.ttf, exception occurred.”, but only warnings.  
I’m  
assuming that’s just because I don’t have those fonts and that it’s not  
a  
show stopper (after all, only warnings).

At the end of post install, I get:

ok.  
setting MAGICK\_CONFIGURE\_PATH to ‘c:/program  
files/ruby/lib/ruby/gems/1.8/gems/RMagick-win32-1.9.2-mswin32/config’.  
setting is only for current user.  
Copying 5 dlls to c:/program files/ruby/bin…done.  
all done.

So, it would seem that everything was okay.

However, when I go into IRB, I get the following error[1]. Any ideas  
what’s  
going on here?

Thanks,  
Matt

It looks like something is requiring RMagick twice. What happens when  
you use

require ‘RMagick’

Note the capitalization. The gem is named “rmagick” but the library is  
“RMagick”.
