Does QtCreator actually work with any Qt 4.x as stated? I have Qt 4.4.3 
installed on Ubuntu Linux (7.04 Feisty Fawn). After qmake runs, I get 
the following errors from make:

====== build errors begin here ==========
In file included from CppDocument.cpp:34:
CppDocument.h:44:26: error: QSharedPointer: No such file or directory
CppDocument.h:60: error: ISO C++ forbids declaration of ‘QSharedPointer’ 
with no type
CppDocument.h:60: error: expected ‘;’ before ‘<’ token
CppDocument.h:104: error: ‘Ptr’ does not name a type
CppDocument.h:239: error: ‘Ptr’ is not a member of ‘CPlusPlus::Document’
CppDocument.h:239: error: ‘Ptr’ is not a member of ‘CPlusPlus::Document’
CppDocument.h:239: error: template argument 2 is invalid
CppDocument.cpp: In member function ‘QStringList 
CPlusPlus::Document::includedFiles() const’:
CppDocument.cpp:137: error: ‘class QStringList’ has no member named 
‘removeDuplicates’
CppDocument.cpp: At global scope:
CppDocument.cpp:224: error: ‘Ptr’ in class ‘CPlusPlus::Document’ does 
not name a type
=========== build errors end =========

Do I need Qt 4.5?
