msDrawRaster(): Unable to access file

Hi, I have many netCDF files I'm wishing to serve through MapServer, each of
them a different time.

My first step is to serve one file, which I can't even do.

The error I get is: 
msDrawMap(): Image handling error. Failed to draw layer named 'RETRO'.
msDrawRaster(): Unable to access file. (RETRO_anthro_nox_1960.0.5x0.5.nc) 

The file definitely has read writes and all, and it's in the same folder as
some of the other data sources I have successfuly read through MapServer, so
I check the file with gdalinfo and it starts out with:

[root at niceguy RETRO]# gdalinfo RETRO_anthro_nox_1960.0.5x0.5.nc 
Warning 1: No UNIDATA NC_GLOBAL:Conventions attribute

Now I read when serving netCDF files through MapServer the file must be CF
compliant("!!!"), so does anyone know if this might have something to do
with it? Before I chop apart my map file, does anyone think this Conventions
attribute 
might prevent my file from being properly read in MapServer?

Thanks for any help!
