[ydl-gen] Building Firefox 4.0 under YDL 6.2 PPC

[Terence G Christopher]

Having installed YDL on my play station 3m and then having tried and 
failed to install my wireless keyboard, I have been following the 
various messages that have developed  over the past 6 months.It is a 
great pity that the incompleteness of YDL and lack of readily accessible 
documentation together with the failure of Sony to permit the machine to 
be readily used and switch between operating systems should destroy what 
could have been a fascinating and enriching  engineering development, It 
is disheartening to see discussions that are unchanged from 30 years ago 
which to me show that all of the talk about object oriented code, and 
clean interfaces was just that talk.I realise that the increasing 
complexity of machines and programmes greatly increases the challenges, 
however Many people such as myself do not want to spend our lives 
fiddling trying to get commonly used software to work on a machine. It 
is to me a measure of the inadequacy of the development and support 
operation. This discourages me from even attempting to use the machine. 
So no my play station  is merely an expensive and clumsy blue ray 
player. What a pity.
sincerely
Terence Christopher
