library files missing on 6.2 upgrade

When attempting to apply the latest patches to 6.2. it reports that several
shared library files are missing when I attempt to freshen the i386
packages, namely:
lbcrypto.so.0
libssl.so.0
linlber.so.1
libldap.so.1

These relate to the following packages:  fetchmail, mutt, pine, python, slrn
and ucd-snmp. Is this significant? And if so how do I fix?

Thanks,

Simon
