  Hrrrmm....I am confused....
  What should not confuse with what ?

  ...an I am not familiar with this damn makefiel system...
  (sorry, not meant harsh...I am just frustrated...see below...)

  I will check this (opti-Flags for autostuff...)

  I am nearly sure, since the whole KDE survives it and the segfault
  happens on a very basic funtionality in blender...

  In other words:
  If you got a bold and a nut, which do not fit together: What is the 
  wrong part ???  ;)

  The one with the following config is the "blender-runs-system":
  CXX=gcc-2.95.3
  CC=gcc-3.2.2
  glibc2.2.5

  The one, on which blender has problems:
  CXX=gcc-3.2.2
  CC=gcc-3.2.2
  glibc2.3.1

  OK?

  I check source/nan_definitions.mk and found nothing special -- or
  dont understand it at all.

  Giving "make" resutls ON BOTH SYSTEMS in

  ====> make all in blender/extern
  mkdir: cannot create directory `/home/mccramer/data/static/home/mccramer/ZZZ/newdir/../lib/linux-glibc2.2.5-i386': No such file or directory

  (on the other system, the other libc-version is mentioned though...

  Hans, as I has already tried to get this make file beast running
  with no success at all, I would be VERY HAPPY, if one could explain
  me how to handle it. I would be able to make bug reports which may
  be more valuable to the community, then.

  Thank you very much for your help and understanding in advance!
