Just a guess, but I think you would get this "projection not named" 
error when a projection object somewhere in your mapfile is missing the 
"proj=..." parameter.

I would suggest making sure your mapfile doesn't contain an empty 
projection object at the top-level or somewhere in one of the layers. 
Also, in my example in my previous message I had forgotten a double 
quote at the end of the ellps line. I don't think that would leads to 
this error message though.
