Qt4/ruby 1.9 install on mac os x Snow Leopard?

Ruby
1

this week end i’ve followed a number of blogs over the net in order to
install Qt4 with ruby 1.9.

my ruby 1.9 is a MacPort one, i’m using Mac OS X SL.

I’ve tried those cmake options :

cmake -DENABLE_QTWEBKIT_SMOKE=off -DENABLE_QTWEBKIT_RUBY=off
-DENABLE_QTTEST=off -DENABLE_QTTEST_SMOKE=off
-DCMAKE_BUILD_TYPE=debugfull
-DRUBY_INCLUDE_PATH=/opt/local/lib/ruby/1.8/i686-darwin9
-DRUBY_LIBRARY=/opt/local/lib/libruby.dylib .

cmake -DENABLE_QTWEBKIT_SMOKE=off -DENABLE_QTWEBKIT_RUBY=off
-DENABLE_QTTEST=off -DENABLE_QTTEST_SMOKE=off
-DCMAKE_BUILD_TYPE=debugfull
-DRUBY_INCLUDE_PATH=/opt/local/lib/ruby1.9/1.9.1/i386-darwin10/
-DRUBY_LIBRARY=/opt/local/lib/libruby1.9.dylib .

$ cmake -Wno-dev
-DRUBY_INCLUDE_PATH=/usr/lib/ruby/1.8/universal-darwin9.0
-DRUBY_LIBRARY=/usr/lib/libruby.1.dylib
-DENABLE_QTWEBKIT_SMOKE=off
-DENABLE_QTWEBKIT_RUBY=off

cmake -DENABLE_QTWEBKIT_SMOKE=off -DENABLE_QTWEBKIT_RUBY=off
-DENABLE_QTTEST=off -DENABLE_QTTEST_SMOKE=off .

without success …
