buccaneer_pipeline failure (ccp4 6.2.0)

Hi, we got around to switching to ccp4 version 6.2.0, but now buccaneer fails from the GUI.  Below is what shows up if you view the com file before execution; and below that the logfile.

Seems to me it's using the wrong python executable;  the first one on my path is certainly nothing to do with ccp4, so now wonder it can't import. 

Shouldn't python be invoked explicitly with its full path?  Where can I set this?  (Mind you, setting it in the Run&View didn't work.)
Cheers

Hi Frank,

it may not be the python binary itself but the PYTHONPATH which is
incorrectly set. After initialising ccp4, mine reads
       tg@slartibartfast:~$ echo $PYTHONPATH
       /xtal/Suites/CCP4/ccp4-6.2.0/share/python:
which is modified around line 231 in $CBIN/include/ccp4.setup

My python binary is /usr/bin/python, and I have used buccaneer without
errors.

Mine reads:
/usr/local/ccp4/6.2.0/ccp4-6.2.0/share/python:/usr/local/ccpnmr/ccpnmr1.0/python

That should work, right?  Where else can I look, for the failing import?  This is a lettuce-fresh install, pulled straight off web and installed with all defaults.

Cheers

And you do have read access to
/usr/local/ccp4/6.2.0/ccp4-6.2.0/share/python/CCP4pipeline.py
(on our installation, the mode is actually 755, but I suppose 644 should
be sufficient).
You can set PYTHONVERBOSE to 1 or higher in the shell you start ccp4i
from to see what python is doing ('man python').
