Travis,

This is really a MapServer question and would be better asked on the
FWTools or gdal-dev lists.

I would strongly encourage you to execute the gdal_merge.py script
from the "FWTools Shell", or to call the same environment initialization
bat file it uses (the setfw.bat file).

Also, in the BIN directory of FWTools there is a gdal_merge.bat.  If you
use that, it will take care of calling the right python executable.

Best regards,
