The fix was meant for the framework version of Qt. Did you try it with that as 
well?

This should actually be in some of the ruby header files.
$ grep TIMEZONE /usr/include/ruby-1.9.1/* -R
/usr/include/ruby-1.9.1/i686-linux/ruby/config.h:#define HAVE_STRUCT_TIMEZONE 1
/usr/include/ruby-1.9.1/i686-linux/ruby/config.h:#define HAVE_VAR_TIMEZONE 1
etc..

What do you get when you grep for these defines?

Might be a bug in the cmake scripts.

This is wrong. It should actually require the qtruby4.so library, not the 
Qt/qtruby4.rb file. On OS X there was a problem, as far as I know, with the 
library having the extension .dylib, not .so.
What you need is this:

/usr/lib/ruby/site_ruby/1.9.1/i686-linux/qtruby4.so 

If it has the .dylib extension, try making a symlink from it to qtruby4.so. If 
this doesn't work, we'll have to think of something.

One solution was to build the library as a 'MODULE' (instead of 'SHARED') in 
cmake, but then we can't link against it anymore. But first try to simply 
symlink it :)
