Compile error with stable snapshoot 2005-11-06

Hi,

while trying to compile the stable snapshot of the 2005-11-06
I got the following error message:

   gcc -O3 -m3dnow -march=athlon-xp -mtune=athlon-xp -mfpmath=sse
   -funroll-loops -fomit-frame-pointer -fforce-mem -fforce-addr
   -finline-functions -falign-functions=4 -mpreferred-stack-boundary=2
   -fPIC -DRUBY_EXPORT -I. -I. -c main.c gcc main.o libruby-static.a
   -lpthread -ldl -lcrypt -lm -o miniruby -O3 -m3dnow -march=athlon-xp

   -Wl,-export-dynamic ./lib/fileutils.rb:1257: [BUG] Segmentation fault
   ruby 1.8.4 (2005-11-07) [i686-linux]
   
   make: *** [.rbconfig.time] Aborted

And "make distclean" after that ended in:

    ./ext/extmk.rb:23:in `require': no such file to load -- rbconfig (LoadError)
            from ./ext/extmk.rb:23
    make: [distclean-ext] Error 1 (ignored)

The system is a Linux (LFS based with the following comppiler installed:

  gcc (GCC) 4.0.2
  Copyright (C) 2005 Free Software Foundation, Inc.
  This is free software; see the source for copying conditions. There is NO
  warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

and

  glibc 2.3.6

I compiled ruby with thsi script:

#!/bin/sh
./configure --prefix=/usr --enable-pthread --enable-shared --disable-static --enable-install-doc && \
make && make install-all

What did I so badly wrong here...?

Thank you very much for any help in advance !
