Nirmal, I think the problem is the lyx.spec has a dependency on "qt", while mandrake provides "qt3". I think that you could/should replce in lyx.spec the line %define frontdep qt >= 2.2.1 with something like %define frontdep qt3 >= 3.1.0
Thanks JMarc.. I made the change above and uploaded the new rpm to www.personal.psu.edu/nug107/lyx .. can you please trasnfer it to ftp.lyx.org? My apologies to those who've had to do the --nodeps... hopefully it should be OK now..
