I think that the latter part of your statement is probably not true.
That error message indicates that you are attempting to create the
OpenLayers javascript before the OpenLayers Map code is added to the
document. 

Note that the default in OpenLayers is to load the Javascript files
asynchronously. If you're not building a single file, and you're adding 
the javascript asyncrhonously, there is no way to ensure that you are
loading the Map object after the Map file is loaded, since the onload
for the main OpenLayers.js will fire before the rest of the Javascript
is loaded. To test if this is the case, you can use a single file
version of OpenLayers. One is hosted on OpenLayers.org:

  http://openlayers.org/api/2/OpenLayers.js

or, to use the latest RC:
  http://openlayers.org/api/2.2-rc2/OpenLayers.js

If this doesn't work, example HTML which is causing the error would be
helpful in further debugging.
