</div>It is a clean new system with only the Ubuntu package installed. I added<br>
900913 to the /usr/share/proj/epsg file. I also just modified the<br>
mapfile and entered the projection parameters in it directly as you<br>
suggested with the same result.<br>
<br>
If you want to try this, download <a href="http://imaptools.com:8080/dl/world.tbz" target="_blank">http://imaptools.com:8080/dl/world.tbz</a><br>
It resides in directory /u/data/ on my system so you would need to<br>
adjust the paths appropriately.<br>
<br>
I've now spent 3 days fussing with this and trying to debug it. I<br>
suppose the next thing to try is to build proj4-4.6.0 on the Ubuntu<br>
system and see if that resolves the issue.<br>
<br>
Thanks,<br>
