A more future-proof solution might be to create a symbolic link from
where skeinforge expects python to be to where it is on your machine:
sudo ln -s <actual_python> <skeinforge_python>
As far as skeinforge ceasing to work, it's likely caused by a well-
known bug that is triggered by moving/renaming the previous file
processed by skeinforge.
To fix, delete the filename in the ~/.skeinforge/skeinforge.csv file
[typically on the second line].
Go!
