Wrong /usr/local/lib/libgcc_s.so.1

[Stefan Karrmann <sk@mathematik.uni-ulm.de>]

Hi,

everytime after updating some packages I have to update
/usr/local/lib/libgcc_s.so.1. Why does this happen?

I use:
Package: gcc-3.3
Version: 1:3.3-2

Package: libgcc1
Version: 1:3.3.1-0pre0

After running:
# apt-get install alsa-source mplayer-k7 mencoder-k7
[...]
I check it again, but:
# apt-get install alsa-source mplayer-k7 mencoder-k7
apt-get: /usr/local/lib/libgcc_s.so.1: version `GCC_3.3' not found
(required by /usr/lib/libstdc++.so.5)

My fix after each installation is:
# ( cd /usr/local/lib && ln -sf /lib/libgcc_s.so.1 . )

Any hints? How can I fix this behaviour?

Sincerly,
