[Scribus] best OS to keep up with scribus, gscript and inskcape dev...

[Tariq Rashid]

although this may sound like an inappropriate question - its not.

i am now starting to produce documents that will need to be as good as
possible as they are for public consumption.

i have always used mandrake (now 10.1) as my workstation as it has had quite
up to date software ... but i am finding it a pain to keep up with inkscpape
and scribus development. 

never mind the fact that mandrake, amongst other major distros, ship
ghostscript 7.07! 

i wonder if a more "source" bases OS is a better idea to keep up with
changes upstream, whilst keeping the local workstation integrated - ie if i
update ghostscript i don't want CUPS printing to break, etc etc 

do people use rolling (non-release) systems like gentoo? freebsd ports?
netbsd pkgsrc? debian testing?

the core question really is which distribution gets the upstream changes in
a timely manner?

thanks
