'''Solution''': This problem occurs under [http://www.apple.com/macosx Apple Mac OS X] if (a) the Apple's python executable on your machine (/usr/bin/python, currently version 2.3.5) is superseded by [http://fink.sourceforge.net/ Fink]'s python executable (/sw/bin/python, currently version 2.5) and (b) you are using [http://delsci.com/rel/099/#MacOSX precompiled versions of PyMOL] (MacPyMOL, PyMOLX11Hybrid or PyMOL for Mac OS X/X11). These executables ignore Fink's python and instead use Apple's - so, in order to run CE Align, one must install NumPy (as well as CE Align itself) using Apple's python. To do so, first download the [http://sourceforge.net/project/showfiles.php?group_id=1369&package_id=175103 Numpy source code archive] (currently version 1.0.1), unpack it, change directory to numpy-1.0.1 and specify the full path to Apple's python executable during installation: <tt>sudo /usr/bin/python setup.py install | tee install.log</tt>. Then, donwload the [http://www.pymolwiki.org/index.php/Cealign#The_Code CE Align source code archive] (currently version 0.2), unpack it, change directory to cealign-0.2 and finally install CE Align as follows: <tt>sudo /usr/bin/python setup.py install | tee install.log</tt>.
