(Something is weird with your character encoding. Or with my character
decoding?)

I think that people either do not run "make check", or they have an X server
at the time of compiling and checking graphic libraries...

Yes.

Hm, which libqt.so? There are 20 libQt*.so! Precisely:
libQt3Support.so     libQtDesignerComponents.so  libQtNetwork.so      libQtSvg.so
libQtCLucene.so      libQtDesigner.so            libQtOpenGL.so       libQtTest.so
libQtCore.so         libQtGui.so                 libQtScript.so       libQtWebKit.so
libQtDBus.so         libQtHelp.so                libQtScriptTools.so  libQtXmlPatterns.so
libQtDeclarative.so  libQtMultimedia.so          libQtSql.so          libQtXml.so

Anyway, objdump on none of them yields anything after piped through "grep icu".

The problem of not finding the icu library was not critical, by the way;
a warning was printed on the console, and the "hello world" program worked
nonetheless.
