Unreferenced Libraries?

[Walter Hurry]

9.1-RELEASE on amd64.

libchk reports the following libraries (among others) as unreferenced:

/usr/lib/libBlocksRuntime.so.0
/usr/lib/libform.so.5
/usr/lib/libformw.so.5
/usr/lib/libgpib.so.3
/usr/lib/libgssapi_ntlm.so.10
/usr/lib/libgssapi_spnego.so.10
/usr/lib/libhistory.so.8
/usr/lib/liblwres.so.80
/usr/lib/libmenu.so.5
/usr/lib/libmenuw.so.5
/usr/lib/libmilter.so.5
/usr/lib/libpanelw.so.5
/usr/lib/librpcsec_gss.so.1
/usr/lib/libstdbuf.so.1
/usr/lib/libsupc++.so.1
/usr/lib/libthread_db.so.3

All these are part of base.

I note that in each case there is a <name>.so symlink pointing to the 
relevant library, as is, I believe, accepted best practice.

Would I be correct in assuming that the reason libchk is reporting these 
as unreferenced is that everything which is actually using them is 
referencing the symlink?

Or is libchk clever enough to resolve symlinks, and there is a different 
reason?
