in that case - 'no matter what' (as far as I can see) - your either going to 
have to remove the packages associated with the newer versions - or take the 
whole thing into your own hands and refix the links every time a new 
revision of a db packages comes out... (please note i could be talking junk 
for all i know here) (okay so it would be as easy as rerunning a script - 
but still :P - for all i know you could make it so the script by default as 
setup runs it does what i suggest - and when passed a force parameter or 
something it ignores version checking)
In the current system - if you want to patch db2 - release a new db2 - your 
going to have to release db3 and db4 as Well - in order to have everyones 
symlinks working nicely? (this is probably the nit that bothers me most)

really depends how often you want to have to tell people to do this I am 
thinking... - whats the law - make the commonest case the easiest? (hmmm 
thinking hoffman coding in the perl 6 reg exp thiny i read for no reason)

same 2 options would be under my system - or postinstall script... *shrug*

well its not me who has to handle the requests 'why is my db install 
broken?'
so I dont realy mind :P (not you either :P)

I dont think it will be quite as rare - but i certainly dont have close to 
the same level of experience as a maintainer as you.
