Unable to upgrade to Lilypond 1.6.3

[Oscar A. Valdez]

Lilypond 1.4.13 is installed from rpm's on my Red Hat 7.2 system.

When I try to upgrade to Lilypond 1.6.3, I get the following:

error: failed dependencies:
        libguile.so.9   is needed by lilypond-1.6.3-1
        libqthreads.so.0   is needed by lilypond-1.6.3-1

So, I've gotten a hold of guile 1.4, but when I try to upgrade (my system has 
guile 1.3 installed), I get the following:

error: failed dependencies:
        libguile.so.6   is needed by gnome-utils-1.4.1.2-1.ximian.1
        libguile.so.6   is needed by g-wrap-1.1.10-ximian.1
        libguile.so.6   is needed by lilypond-1.4.13-1
        libguile.so.6   is needed by gnucash-1.6.6-1.ximian.1
        libguile.so.6   is needed by gnome-games-1.4.0.4-1.ximian.1

Am I trapped in unresolvable dependency hell? Can someone point a way
out?
