I don't understand the full technical aspects of what you wrote, :-) but what you wrote matches the particular error messages I'm seeing.

Although I asked the question, I was leaning toward /opt/trinity/lib/trinity not being necessary in /etc/ld.so.conf because the equivalent /usr/lib/kde[3] never was needed with KDE3 and everything works as expected.

The peculiar thing about this problem is only kword and kpresenter are affected. Possibly there are other "undefined symbol" problems in my builds that I have not yet noticed, but I'm guessing kword and kpresenter are not linking correctly during my builds. I don't know how to debug further or what to look for.
