only another error message...
src/lyx: symbol lookup error: src/lyx: undefined symbol:

ok, this is definitely a qt error. even qtconfig won't launch, it
gotta be qt related. but what exactly? i tried removing &
re-installing all qt packages and many others; and i wasn't able to
find duplicate qt libs, but i'm not really an expert in libs and devs.

too bad, that's gonna be a CV made with ms-office. yak... ;-)

thanks for the feedback folks
