Problem with upgrading to gnucash 1.8.5

[Paul B.]

I have problems with upgrading my 1.8.1 version to 1.8.5.
I'm using RH9 and 1.8.1 works fine. When installing I'm getting 
following errors:

rpm -Uvv gnucash-1.8.5-1.RH8.0.i386.rpm
.....
D:  Requires: gnucash = 1.8.1                               NO
D: package gnucash-backend-postgres-1.8.1-3 has unsatisfied Requires: 
gnucash =1.8.1
D: closed   db index       /var/lib/rpm/Depends
error: Failed dependencies:
         libguile.so.9 is needed by gnucash-1.8.5-1.RH8.0
         libqthreads.so.0 is needed by gnucash-1.8.5-1.RH8.0
         gnucash = 1.8.1 is needed by (installed) 
gnucash-backend-postgres-1.8.1-3


Any clues?
