oh yes, but we have luck and it is NOT the standard Installation

Sorry, perhaps my bad English, mostly all users of my program didn`t know
how to install a program.  They didn`t know what a paket manager is. 
And just this last week I have the first time of my project-life setup a deb-Installer.

I need no help for porting, I will simple not do this work until it is really needet !
And I think, the next 10 years it is not needet !

I do that perhaps in some years, perhaps not .

I checked it just last year and there are the most packages that I need, are not ported, 
so the twisted ( web, mail, words )  packages. Also reportlab and pygtk seems have some trouble
with unicode and str. Other are the database driver. And for a lot of packages I didn`t know it, 
perhaps is there a central internetsite who ported packages are listed ?
(gtkmozembed, gtksourceview, imaging with sane backend, and so on !! )

And some of the other packages will never ported, I must do that then myself.

And then, it is only a lot of work for me ( new installer, new dependencies) for no
advantages. My Project is very soon 3x compatible, mostly only some 1000 prints must
 changes, that can do a script. But last year also they say, that python3 is slower , I don`t know.
And really, a lot of work only for so few changes, that is not my way. 

2 Years ago I thought, it was a good and nice thing to change to python3, but for me it is now 
clear, that I must wait 5 or 10 years to port my project.
