Hi Joseph,

Several comments that might help....

These warnings may not be directly relevant here, but they sound like  
there's a config problem with xdvipdfmx. Are you running a very  
recent update? If so, you may need to move the dvipdfmx.cfg file from  
(SOMEWHERE)/texmf/dvipdfm to (SOMEWHERE)/texmf/dvipdfmx, to match  
recent changes in the dvipdfmx and xdvipdfmx drivers.

(And if you do copy/move such a file, remember to update the TeX  
filename databases using texhash or the MikTeX equivalent... you  
didn't specify exactly what TeX system you're using.)

You can try changing the PDF version setting in the config file; see  
the "V" entry, probably the first option that's specified in  
dvipdfmx.cfg if yours looks anything like mine. You can change it  
from "4" to "6" to suppress this warning.

Here, xdvipdfmx is trying to use Ghostscript to convert the image  
format. I think it's doing that to try and re-encode it as PDF 1.4;  
but GS apparently isn't installed or isn't found on your system.  
Result: it ends up without a usable file.

Changing the PDF version # in the config file may stop it from trying  
to do this, and allow you to include the page directly.
