I've put together a quick zoularis package in Solaris pkg format,
based on zoularis 20010323.

It's only been tested on an UltraAX-e and Ultra-250 both running
Solaris 8 MU 4.

The package can be downloaded from: 

 http://ethmoid.org/pkg/sparc/NBSDpkg.1.0.SPARC.pkg.gz

To install:

 gunzip NBSDpkg.1.0.SPARC.pkg.gz
 pkgadd -d NBSDpkg.1.0.SPARC.pkg
# XXX pkgtools sometime look in /usr/local/bsd
 ln -s /usr/bsd /usr/local/bsd 
 
You need to have these packages installed:
 
gcc (either Sun's SFWgcc or sunfreeware.com's SMCgcc and whatever
other pkgs needed to get gcc running)
 
SUNWbcp
SUNWscpr
SUNWscpu
SUNWxcu4
 
SMCdiffu (GNU diffutils, needed for deinstalling pkgs)
(GNU diff will need to be ahead of /usr/bin/diff in your path)

SUNWgpch (if you use SMCgcc)

And a recent copy of pkgsrc, of course.

To install packages:

export PATH="/usr/bsd/bin:$PATH"
cd </path/to/pkgsrc/your_pkg>
bmake install
