No, I cannot do it:
>>> from mapnik import Projection as P
>>> P('+init=epsg:32635')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
RuntimeError: failed to initialize projection with:+init=epsg:32635
>>>
Proj4 string is really accepted now. I seem to get what I want that way even
if epsg codes do not work at the moment. However there is something odd with
coastline. Images done with nik2img are missing part of coastline, while
genarate_image.py gets them all from the same database.

Aihe: Re: [Mapnik-users] Nik2img.py stopped reprojecting
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
