In version 1.59-6,  docbook-style-dsssl requires openjade = 1.3.  I
installed it on a system which had openjade-1.3-6 (from RH 7.0).  That gave
an error message:

install-catalog: "/usr/share/sgml/openjade-1.3/catalog" does not exist or
is empty.

Now, openjade-1.3-6 has its sgml files in /usr/lib/sgml, and there isn't
any catalog there as far as I can see.  This is introduced in some release
after 6, and no later than 12 (from Fisher).  (I haven't checked beta1 and
beta 2 to see where it changed.)

So I suggest you add a 

  Requires: openjade >= 1.3-12

or whatever the precise release is if you want to be more fine-grained.

(It should still also requires the VERSION to be exactly 1.3.)
