Problem installing LilyPond

[Colin Germond]

I am running the Mandrake 8.2 installation of Linux.  I used the Red Hat lilypond-1.6.5-1.i386.rpm (I couldn't find lilypond in the Mandrake cooker directory).  I received an error during installation which is obviously fatal as lilypond gives the following error: error while loading shared libraries: libqthreads.so.0 Can you tell me where I can find this to install it? Many thanks Colin Germond
