Map file test fail

[Joaquim Pinto da Costa]

Hi
As a new user in a new mapserver project I'm testing my map file with
shp2img. The results weren't very encouraging.

C:\php>shp2img -m "C:\Program Files\Apache Group\Apache2\htdocs\AlAtlas\map\AlAt
las.map" -o test.png
msProcessProjection(): Projection library error. No such file or directory <br>

Is this a problem with proj4 ? Although I have the projection defined
at the map and layer levels all data is using the same projection.

In fact I didn't manage to get a map with data with different
projections but the current map file works perfectly with the HTML
interface.

Any clues where to start? Is it an absolute necessity to pass the
shp2img test to have proj4 working?
