CVS-Blender: Again help needed

Hi,

Things gonna strange…

Is there anything which was recently updated outside
the Blender source tree, which is needed as prerequisite ???

I understand, that Blender itself made from CVS-osurce
not always works (it is a work in progress…) but now
building blender itsself fails while interpreting the SConstruct
file with:

gcc (GCC) 4.0.2

scons: Reading SConscript files …

target_scanner = SCons.Defaults.ProgScan)
File “/usr/lib/scons/SCons/Builder.py”, line 147:
ret = apply(MultiStepBuilder, (), kw)

The INSTALL file is of November 2004 – no longer updated?
The README is talking of Blender version 2.28a…and is of
August 2004.

My tools:
gcc 4.02, python 2.3.5,
SCons by Steven Knight et al.:
script: v0.96.90.D001, 2005/02/15 20:11:37, by knight on casablanca
engine: v0.95.D001, 2004/03/08 07:28:28, by knight on casablanca

What did I so badly wrong that building blender fails
from one day to another ?

Thank you very much for any help in advance!
Keep hacking!

Sorry, can’t help (I use the GCC/CygWin/Make combo, which still works fine, though it ends up making a Blender build called 2.40alpha :D), but I suspect you might find more help/response here.
