Can't find libc.so.6 though it's there

[Florian Hühn <acpi at trafficmanager dot org>]

Hi all,

i just upgraded form Glibc-2.2.2 to Glib-2.3.5 (and gcc from 2.95.3 to
3.4.5).
Until now most programs seem to run fine with the new glibc. But there
are now some programs that claims there would be no glibc.so.6. One of
these is agrep:

me@linux:~ > agrep
agrep: error while loading shared libraries: libc.so.6: cannot open
shared object file: No such file or directory
me@linux:~ > ldd /usr/bin/agrep
        linux-gate.so.1 =>  (0xffffe000)
        libc.so.6 => not found

Oher programs like gkrellm in addition reports libpthread and other
glibc-librarys as missing (libgtk and other non-glibc-libs are found
properly).
I couldn't figure out a way to get them running again except recompiling
them. The problem is: I'm really not able to check and recompile every
single program in the system.

Has anybody an idea why these programs can't find the glibc?
Or anaything i could test?

More results of tests i did are attached.

Thanks
flo


Versions used:
Linux kernel 2.6.7 from kernel.org (compiled with gcc 2.95.3)
Gcc 3.4.5
Glibc 2.3.5 with glibc-linuxthreads-2.3.5
For compatibility reasons i used these ctype_b and errno patches:

Some tests i already did:
