Standalone Vidalia 32-bit Linux doesn't include libQtGui.so.4 or libQtXml.so.4
Using vidalia-standalone-0.2.21-gnu-linux-i686-en-US.tar.gz
$ ./start-vidalia
./App/vidalia: error while loading shared libraries: libQtGui.so.4: cannot open shared object file: No such file or directory
When I apt-get installed libqtcore4 libqtgui4 then it got farther, but it was next missing libQtXml.so.4.
So then I apt-get installed
libqt4-network libqt4-xml libqtcore4-perl libqtdbus4 libqtxml4-perl
libsmokebase3 libsmokeqtcore4-3 libsmokeqtgui4-3 libsmokeqtnetwork4-3
libsmokeqtxml4-3
and then it worked.
