Jukka,

Can you do:

$ python
 >>> from mapnik import Projection as P
 >>> P('+init=epsg:32635')
<mapnik.Projection object at 0x236030>

If not then you've got a problem with the proj 4 epsg files being found.

If you can then there must be a string parsing bug in nik2img.py

Also,

I just tried this:
-p '+proj=utm +zone=35 +ellps=WGS84 +datum=WGS84 +units=m +no_defs'

and I can confirm a bug that should be fixed in r.263. Can you svn up  
and let me know?

Thanks,

Dane
