libmapnik compiled without proj support

[Marcos Sánchez Provencio]

In what it seems a regression, libmapnik is compiled without proj support in ubuntu 22.04 (it was supported in ubuntu 20.04). The error from the (working in 20.04) program is:

RuntimeError: Cannot initialize proj_transform for given projections without proj4 support (-DMAPNIK_USE_PROJ4): '+proj=utm +zone=30 +ellps=GRS80 +towgs84=0,0,0,0,0,0,0 +units=m +no_defs'->'+proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs'

`getbuildlog mapnik last` shows:
Note: will build without these OPTIONAL dependencies:
   - proj (Proj.4 C Projections library | configure with PROJ_LIBS & PROJ_INCLUDES | more info: http://trac.osgeo.org/proj/)^[[0m

The attached python script works in ubuntu 20.04, produces said error on ubuntu 22.04

I have reproduced the same error with the attached python test in ubuntu 22.10 beta

Status changed to 'Confirmed' because the bug affects multiple users.

renderd log shows the same error on just-installed Ubuntu 22.04.2 LTS.
