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