It seems blender2crystal managed to find and run bootstrap but then python wasnt able to load the crystalspace and cel modules. This could be due to several reasons.
You can check http://www.crystalspace3d.org/tikiwiki/tiki-index.php?page=Prerequisites
for instructions on what to install and how to check everything is in its place for the python cs bindings. Most probably you dont have swig installed, if so you can try moving the file cel/scripts/blcelc.py to cel directory and CS/scripts/python/cspace.py to CS directory.
Also check on configure if Python SDK is found and usable, else set the PYTHON variable to the full path to your python.exe file (ie, something like c:\Python24\python.exe) before running configure.
hope this helps
if nothing else and you dont mind using pre-generated binaries you can get compiled CS and cel with python included from http://b2cs.delcorp.org/files/cs060706.zip
to start playing around...
