Ok, I had a feeling that a problem like this would be a system or build one.
Eureka, I just started to gdb blender, the debugging source is packaged
and installed as a separate rpm.
I looked up "BPy_init_modules( void )" in kdevelop3, using the patched
sources that are used to build and tried to enter a break on "bpy.c:179"
and gdb couldn't find it.
So I looked in "find /usr/src/debug/blender-2.55.32862/ -name bpy.c" and
it doesn't exist.
This must be a result of the " -DWITH_PYTHON:BOOL=off" statement. I will
examine build logs and play around a bit to see what I can find but this
is a bug, you at least need to put a warning.
actually supposed to do? I'm trying to build blender using systems
python3 which combination of the two flags would I need.
"OPTION(WITH_PYTHON_INSTALL       "Copy system python into the blender
install folder" ON)" I take this to mean that the systems python3 will
be packaged with blender.

"OPTION(WITH_PYTHON        "Enable Embedded Python API" ON)" This I
think is the equivalent to scons's "WITHOUT_BF_PYTHON_INSTALL: dont
install Python modules if true (yes|no)" .

So the reason for strace not picking up the scripts loading is because
there wasn't a bpy.c to find it.
I'm building with " -DWITH_PYTHON:BOOL=on"  and
"-DWITH_PYTHON_INSTALL:BOOL=off" I think I had a build failure when I
tried it before.
Will report back.
