still compiling problems: sgml

["Andreas J. Guelzow" <aguelzow math concordia ab ca>]

I am nearly successful with compiling (well technically it completed but 
I hate errors on the way, even if only 200  ;-)  :

What is this about:

---------------------------------------------------
cd . && perl make-docbook.pl func.defs > func-list.sgml
cd . && perl make-index.pl func.defs > func-index.sgml
cd . && cat func-header.sgml func-index.sgml func-list.sgml 
func-footer.sgml > functions.sgml
cd . && db2html gnumeric.sgml
TMPDIR is DBTOHTML_OUTPUT_DIR5272
Using stylesheet: 
"/usr/share/sgml/docbook/dsssl-stylesheets-cygnus/stylesheets/cygnus-both.dsl"

input file was called gnumeric.sgml -- output will be in gnumeric

working on ../gnumeric.sgml
jade:../gnumeric.sgml:1:66:W: cannot generate system identifier for 
public text "-//GNOME//DTD DocBook PNG Variant V1.0//EN"
jade:../gnumeric.sgml:20:0:E: reference to entity "BOOK" for which no 
system identifier could be generated
jade:../gnumeric.sgml:1:0: entity was defined here
jade:../gnumeric.sgml:20:0:E: DTD did not contain element declaration 
for document type name

....

jade:../introduction.sgml:326:24:E: element "GUIMENUITEM" undefined
jade:I: maximum number of errors (200) reached; change with -E option
jade:/usr/share/sgml//docbook/dsssl-stylesheets/html/dblink.dsl:203:1:E:

jade:/usr/share/sgml//docbook/dsssl-stylesheets/html/dblink.dsl:203:1:E: 
XRef LinkEnd to missing ID 'print'
jade:/usr/share/sgml//docbook/dsssl-stylesheets/html/dblink.dsl:203:1:E: 
XRef LinkEnd to missing ID 'print-preview'
about to copy cascading stylesheet and admon graphics to temp dir
about to rename temporary directory to gnumeric
cd . && cp gnumeric/index.html .
---------------------------------------------------

Am I using the wrong style sheet, if so where do I find the right one???
