You can set the path in your user-config.jam file. Something like:
using boostbook : /usr/share/xml/docbook/stylesheet/nwalsh/current ;

I didn't implement it, so I can't say for sure. Probably just to have
a single method for all platforms. It originally required you to
explicitly specify the paths, checking known locations is a pretty
There are problems with relying on the standard catalog. There's a
fairly good chance that on some machines it won't be correct, or will
be missing an entry. For example, if the stylesheets were installed
manually or the packaged versions were uninstalled badly.

To automatically support catalog files, it'd need to do is to first
check that the catalog exists and then check that it correctly maps
the relevant paths to existing local files. Or perhaps there could be
some special parameter to say, 'use this catalog', although it'd also
need to somehow know which urls are mapped in the catalog. We're
probably short on volunteers willing to implement such a thing, so I
think the solution is just to add a check for suse's path.
