the profile version number goes into the metadata.xml file in the profile itself.

actually, as i coded it GS _does_ fail over to using the version.txt version 
number if there is no version explicitly specified in the metadata.xml file. 
i've since become convinced, however, that this should not be the default 
behaviour; you should have to explicitly specify if you want to use the 
product version as the profile version.  i don't think anyone has actually 
changed this in the code, but i haven't been paying much attention recently.
