up2date problem after upgrading from fc2 to fc4

[Perazim]

Upgraded from fc2 to fc4 ok. Later, when running up2date, it generates
"unresolved chain of dependancies" when applying fc4 updates. They are:

xxx requires libstd++.so5
xxx requires libstd++.so5(CXXABI_1.2)
xxx requires libstd++.so5(GLIBLPD_3.2)

where xxx is Bestcrypt, Maelstrom, Moni, abiword,apt,chromium, gpdf,
grip,tora,tunracer

This error is generated whenever any of the c packages are attempted to
be updated .... cpp 4.0.0-8 to cpp 4.01-4.fc4

How do I resolve this?

Thanks,
L. Baker
