In fact 1.5 is still development version and it is not for users.
Fact that 1.5 is highly usable and stable is only good sign for developers 
they do the best but is not any promise it will be all the time before final 
release.

So dont expect any "userfriendly" installation process now.
It is your risk that you use 1.5 already and you must fit requirements, not 
developers.
