linux - libstdc++.so.6: cannot handle TLS data

I have an application compiled
at:

• gcc version 4.1.2
  20061115 (prerelease) (Debian 4.1.1-21)


• Linux debian
  2.6.18-5-686 #1 SMP Fri Jun 1 00:47:00 UTC 2007 i686
  GNU/Linux

and it runs
well.

Now I want to run it
at:

• Linux
  2.4.20_mvlcge31-tomas #7 Thu May 7 11:33:21 CEST 2009 i686
  unknown

I got following
errors:

libstdc++.so.6: cannot
handle TLS data

From
the web I saw someone suggested to do this: export
LD_ASSUME_KERNEL=2.2.5

I tried but
get even more errors:
ls: error while loading shared libraries:
librt.so.1: cannot open shared object file: No such file or
directory

Who can help me with
it? thanks
