You can just copy the MoinMoin dir to the new location.
But then remove all .pyc files. Have a look at the output  of
cd  /usr/local/lib/python2.7/dist-packages/MoinMoin
find . | grep .pyc$

if this is the right filter do a
rm `find . | grep .pyc$`

(these are backticks, to enclose the right command)

or make it a list and remove it by a loop

Make sure that the directory and files could be read by the service user
e.g.
cd  /usr/local/lib/python2.7/dist-packages/
chmod -R a+rX MoinMoin

you get that message if your configured default python can't find the
library

same happens likly with
> python
>>> import MoinMoin

Have also a look into the script

cat /usr/local/bin/moin

May be there is also a path set,

for comparison the content of that file we deliver:
http://hg.moinmo.in/moin/1.9/file/4790615ddfb6/setup.py#l172
