I've been caught by that one...

...and here's the problem: if I've installed a "exp" package(s), I'm not always sure what dependencies it installs
(maybe that's just sloppiness/inattention on my part). Then when I want to update something else and prevent setup from
"downgrading" my "exp" package(s) to "current", I'm never quite confident that I'm not going to break something by
keeping/not keeping some dependent package.

To give an example, I have installed the exp gcc 3.4.1 and mingw-gcc 20040822 packages. Now I see I have libtool-devel
1.9f_20041024 installed, whreas setup wants to change that to 1.5.10. I suspect, but am not sure, that this is a
dependancy of my "exp" gcc and should therefore keep the current version. Is there a safe way to find out?
