? essentially I agree but why would uninstalling a program that was
installed into ONE directory under /opt be a problem? There were
obviously NO modifications to the system outside of that directory (I
usually make sure of it by not installing as root)

yeah, but installing into /opt/package-version works on pretty much
all unix(like) OSs regardless of what package system you use. You're
right that it's not a good general solution but it's pretty handy for
small-scale installations (few programs and/or libs). Plus since
everything goes into one directory you're pretty sure that the rest of
the system is not affected (not sure how good is checkinstall in this
area, it tries to check what the install did but I'd rather have install
NOT touch the rest of the system, whether under supervision or not).
