Usually they're Bourne shell script.

You can see the scripts used by cups-libs with this command:
rpm -q --scripts cups-libs

Always a good call! :-)

That's it.

Probably the miscreant package was not an RPM, since otherwise you
would have a conflict and it wouldn't install "cleanly".

RPM can be used to show that something unexpected was changed with
your original RPM if you use this command:
rpm --verify lzo

I would advise also doing "md5sum /usr/lib/liblzo.so.1*" to make
really sure they're the same.

As both files have the same date, I might be wrong in my suspicion
that that was the date the file replaced the symbolic link.

Yes!

Good, thanks!
