undefined symbol

[Xun Cheng <xun cs ucsb edu>]

I'm trying gnome v0.20. Downloaded and installed those RPMS.
But I can run panel and background-properties (not sure about other
progs). The error message is
 
panel: error in loading shared libraries
: undefined symbol: __eh_pc

I don't know which library has problem (any way I can find out?).
The following is the result of ldd panel

        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x2aaaa000)

I'm guessing my libstdc++.so.2.8 has problem because I can run
keyboard-properties and it doesn't load libstdc++.

Could anyone give me some help?

thanks
