Sorry, seems that I had messed up my config somehow, now GDAL does not 
work anymore inside the EPD Python. Hmm, have to make some clean 
tests...

Trying Unison via the GMane NNTP now, but weird that nabble has your 
last answer already for long time, whereas GMane still does not show 
it. Does the NNTP pull the mailing lists on a low frequency.
Man, I think it's 10 years ago or so since I have used NNTP. Used it a 
lot in my first net years, 94/95 ;)
Thanks for the GMane tip, the nabble reply web interface does not even 
quote properly, very strange thing, or i do something wrong.
