Hi,

1. you can use kdevelop but there are also other alternatives like eric, netbeans,... but for me kdevelop fits best for my purposes.

2. you can also use kdevelop for perl but maybe eric or others might be better with the syntax completion because kdevelop supports syntax completion only in C++ as far as I know.

3. the new license model of Qt4.5 allows now to develop applications under the LGPL but before GPL was also allowed. I don't know if it is a good idea to update Qt4 you could ran into a lot of troubles because kde4 and yast relied on Qt4 and maybe you must recompile them work with the new Qt version or install Qt into a different location. Maybe someone has tried it yet and can give a better advice here.

Hope this helps
