Hmmm, its not the responsibility of ldconfig to recreate *.so files

What information is missing? Does clamav have a DT_SONAME (see  
readelf.a)

Note also that rpm can fail to run ldconfig while upgrading.
The very last ldconfig in a transaction can be skipped wrongly
if the packages happen to be arranged that way.

Run /sbin/ldconfig manually if that bothers.
