So here's the deal.  I still don't know why, but the file /etc/xml/ 
catalog is missing some entries on my system.  A friend is installing  
Fedora 8 and appropriate packages to see if he can repeat this.

xmlto is a shell script that executes xsltproc with a parameter  
telling it NOT to go to the net (explaining my odd error message), so  
it uses /etc/xml/catalog to find a locally cached copy of the style  
sheets instead.  My catalog file was broken, so it failed.  If this  
happens to you, this can be worked around by adding the following  
before the last line of /etc/xml/catalog:

 <rewriteSystem systemIdStartString="http://docbook.sourceforge.net/release/xsl/current 
" rewritePrefix="file:///usr/share/sgml/docbook/xsl- 
stylesheets-1.73.2"/>
 <rewriteURI uriStartString="http://docbook.sourceforge.net/release/xsl/current 
" rewritePrefix="file:///usr/share/sgml/docbook/xsl- 
stylesheets-1.73.2"/>
 <rewriteSystem systemIdStartString="http://docbook.sourceforge.net/release/xsl/1.73.2 
" rewritePrefix="file:///usr/share/sgml/docbook/xsl- 
stylesheets-1.73.2"/>
 <rewriteURI uriStartString="http://docbook.sourceforge.net/release/xsl/1.73.2 
" rewritePrefix="file:///usr/share/sgml/docbook/xsl- 
stylesheets-1.73.2"/>
 <system systemId="log4j.dtd" uri="file:///usr/share/sgml/log4j/log4j.dtd 
"/>

This is a manual merge of the key lines from fc6 with the pathnames  
from Fedora 8.  (The last line was along for the ride, I don't think  
it's relevant here but left it in.)  If someone who's running a Fedora  
8 system successfully would privately send me a copy of their file to  
look at, I'd appreciate it.

With that change, GNURadio is building and running fine now.

Thanks!
