[MacRuby-devel] macruby_deploy and nokogiri - LoadError on some mac

[Eloy Duran]

Hi,

It seems that the nokogiri gem that you are bundling has been compiled against a iconv installation in /opt/local (macports|homebrew). Some users probably have it as well which is why they wouldn't complain, but people with a default osx installation don't. Here's what it does on my system, which uses only default system libs:

% otool -L /Library/Frameworks/MacRuby.framework/Versions/0.11/usr/lib/ruby/Gems/1.9.2/gems/nokogiri-1.4.4/ext/nokogiri/nokogiri.bundle
/Library/Frameworks/MacRuby.framework/Versions/0.11/usr/lib/ruby/Gems/1.9.2/gems/nokogiri-1.4.4/ext/nokogiri/nokogiri.bundle:
	/Library/Frameworks/MacRuby.framework/Versions/0.11/usr/lib/libmacruby.dylib (compatibility version 0.11.0, current version 0.11.0)
	/usr/lib/libexslt.0.dylib (compatibility version 9.0.0, current version 9.13.0)
	/usr/lib/libxslt.1.dylib (compatibility version 3.0.0, current version 3.24.0)
	/usr/lib/libxml2.2.dylib (compatibility version 10.0.0, current version 10.3.0)
	/usr/lib/libiconv.2.dylib (compatibility version 7.0.0, current version 7.0.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.2.10)

As you can see, it references /usr/lib/libiconv.2.dylib, not /opt/local/lib/libiconv.2.dylib. So it's probably best to only compile against system versions.

To make sure this doesn't happen in the future, you should always test your app on clean installs of the system. It's pretty easy to keep a spare HD around with multiple version installs from which you boot and test the whole process.
