What version of cgkit is this (alpha8)? Is your OS 32bit or 64bit? Is 
there anything "special" about your system (like: are there several 
versions of Python available, is it a custom build, etc)? Where does the 
Boost library come from (it must be built against the correct Python 
version)?
Was there any warning when building the C++ support library or the 
wrappers? Which optional libraries did you include in the build (lib3ds, 
CyberX3D, ...)?

Can you also try:

 >>> import cgkit._core

Does this also segfault? (this is the module that contains the C++ 
wrappers which is probably the only thing that can actually segfault, 
but I saw that the bounding box unit test succeeded and that one is 
using the module as well, so maybe the crash is somewhere else)

If this should succeed, can you try importing individual modules instead 
of cgkit.all (such as cgkit.cgtypes)?
Otherwise have a look where the dependent libraries come from using ldd 
on cgkit/_core.so (this is wherever you installed the package or still 
inside the build directory).

By the way, there is a script all.py which just does that.

This is not related to your problem, but I have changed those variable 
names (I haven't checked cgkit with Python 2.6/3.0 yet).
I noticed that the source archive also doesn't contain the data 
directory which contains files that are used by some tests. I have 
changed that as well, so that the next release will include those files.
