The environment this problem exposes itself is cygwin. The problem is 
that environment variables cannot be set correctly. It's a problem for 
the doc build because before xsltproc is invoked, the CATALOG 
environment variable needs to be set to point to a particular file; 
otherwise, xsltproc cannot resolve certain stylesheet URLs correctly.

At least, that's my recollection, but Daniel has more recently grappled 
with this problem. Maybe he can jump in.
