This indicates that the moin script cannot load the xapian package, which is 
provided by the xapian-bindings code. You can either try and configure the 
environment using PYTHONPATH or just change the moin script to specify the 
location of the xapian package. It is probably easier to do the second of 
these things.

So, in /srv/moin-private/python-env/bin/moin you can follow the advice and 
edit the code as follows:

#Fix and uncomment those 2 lines if your moin command doesn't find...
import sys
sys.path.insert(0, '/srv/moin-private/python-env/lib/python2.7/site-packages')

Here, I made a guess at where you have installed the xapian package, but you 
will have specified this using PYTHON_LIB when configuring the xapian-bindings 
code. For the above guess, you would have needed to have given PYTHON_LIB 
as...

/srv/moin-private/python-env/lib/python2.7

So, in the moin script you would add whatever PYTHON_LIB was with an extra 
"site-packages" component at the end.

I hope this helps.

P.S. It might be best to run sudo using the -u option to specify the user. 
Otherwise, apart from the risks with running as root, the index files will end 
up with root ownership (most likely) and won't be readable by the wiki.
