That seems fishy to me. Libxml supports two kinds of catalogs:
* The (older) SGML catalogs. If you use SGML catalogs, set the env
variable SGML_CATALOG_FILES
* XML catalogs which is superior than SGML catalogs. If you use XML
catalogs, set the env variable XML_CATALOG_FILES
However, in your case, you seem to use *XML* catalog, so
SGML_CATALOG_FILES is wrong. Did you try it with the env variable
XML_CATALOG_FILES?

I can't recommend the --catalog option. According to --help:
--catalogs : use SGML catalogs from $SGML_CATALOG_FILES
otherwise XML Catalogs starting from
Maybe xmllint is confused, because it expects SGML catalog files, but you
gave him XML catalog files. Use either of them, but not a mixture. :)

I haven't look much in the details, but maybe debug your *XML* catalog
first. You can do this with xmlcatalog (one line):
xmlcatalog PATH_TO_YOUR_XML_CATALOG \
"http://www.oasis-open.org/docbook/xml/4.5/docbookx.dtd";
The above line outputs the path to your local DTD. If you get "No entry
for ..." then you should look into your XML catalog again.
You can also debug the catalog processing with the environment variable
XML_DEBUG_CATALOGS. In this case, xmllint is a bit more verbose. :)
Hope these ideas help a bit,
Tom
