After several frustrating hours, I've managed to work around the error. Let 
me try to explain.
 
One big difference between the source distribution and the git cloned 
version is the former contains a lot of pre-generated files, namely all 
those in sip/cpp and sip/gen. These are not cleaned with "build.py clean", 
so calling "build.py etg" works out of the box because it doesn't do much. 
However, if you do a "build.py touch" and then
"build.py etg" you get the error mentioned in the last post, or one similar 
to it. To reproduce:
 

   - Download the source (or git clone).
   - build.py clean
   - build.py dox
   - build.py touch
   - build.py etg

You'll get the following:

(Note that this is after fixing errors created by the missing, 
undocumented dependencies "dot.exe", "touch.exe", "C:\Cygwin", which I'll 
document in another post.). 
 
The workaround was simple, once I figured out the problem is caused by the 
documentation the "etg" command is trying to build. Simply use the 
"--nodoc" option for all commands, e.g. "build.py. etg --nodoc". Sadly, 
this means you can't view the documentation, which is not fun if you're 
trying to improve the documentation.
 
I don't know the build system good enough to fix this issue. Hopefully the 
explanation above might help someone else who might be able to fix it.
 
I'm using Windows 7.
 
By the way, should this type of thing be submitted as tickets (issues), or 
is it too early in development to submit Phoenix issues?
