   I'm just trying to get OGR with ODBC working  on the win32 binaries.  I
tried the shp2img on my map file though and get the following error

>C:\msapps>shp2img -m c:\apache2\htdocs\ms4w\apps\cbm\map\cbm.map
>msProcessProjection(): Projection library error. invalid projection system
 >number <br>

Would i have to recompile mapserver with OGR??
