I see. So, probably find or ls or something smarter about symlinks
will actually be needed.

How do you handle the multiple versions, though? If you have
/opt/qt-3.3.8 and /opt/qt-3.3.7 with /opt/qt -> qt-3.3.8, then `find
/opt/*/bin -type d' (what's in the book right now) will still add all
those paths and prepend them to PATH.
It might just be best to drop the globbing altogether and assume that
if you install something in /opt, then you will setup the appropriate
PATH, PKG_CONFIG_PATH, ld.so.conf, etc. In that case, we can just have
a single test for /opt/bin and /opt/lib/pkgconfig just like the
/usr/local cases.

I agree. I don't think your setup is crazy at all and I think a lot of
people use it. I'd like to support that here as best as possible.
