Hi Roger,

Not every buildout is itself an egg. So in any case we need a fallback.

In my use case I plan to set the version manually in the pot_header 
template. So I don't need the version lookup.

i18nextract.main() initializes POTMaker this way:

     # setup pot maker
     maker = POTMaker(output_file, '')

The second argument is the path that is used by 
POTMaker._getProductVersion() to look up a 'version.txt' file. Maybe we 
could use a better path than ''. But I'll leave it to someone else to 
figure that out.

Debugging doesn't help much if we don't know all use cases.

What about testing it like this:

We remove the 'else' part and wait until someone complains. In that case 
we have a scenario for testing and fixing the issue. If nobody 
complains, the 'else' part was indeed useless.

The current code doesn't work for me because 'src' is found but not the 
right place to split the path.
