well, being the clever bugger that I am - I decided to install mplayer on mandrake 9 =- had it installed nicely on a previous build which starting doing odd things so rebuilt from scratch...
got everything I needed working right and happily... then tried to work out what dependencies were missing and install them.
Bad idea.. it somehow deleted the qt sym links from where they were supposed to be (have just spent the last hour trying to find them and fix them)
it's not a nice surprise first thing in the morning - but at least it's forcing me to actually learn what the hell I'm doing!
