the upgrade was:

i386-pc-linux-gnu-...

the upgrade was:

i386-pc-linux-gnu-3.3.5-20050130 => i686-pc-linux-gnu-3.4.5

Then I wanted to rebuild files using the libstdc++ with:

revdep-rebuild --library libstdc++.so.5 -pv

it made a list of packages to rebuild, and when calling emerge, it throws:
/usr/bin/python: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory

Then I tried:
fix_libtool_files.sh 3.3.5-20050130 --oldarch i386-pc-linux-gnu

it fixed something, but not this error.

the library is there, so it has to be someting with wrong paths:

borg lib # find ./ -iname "*libstdc++*"

What should I change, to fix this? (Yes, I've searched for older topics on this... maybe I've found wrong ones, since it didn't help)
Thanks in advance.
