It needed libapr, but that was available as a secondary subversion-deps 
source bundle. Getting a standalone svn server running locally was a bit 
of a no-brainer, I /really/ didn't want to risk messing up the version 
of Apache on the system in question.

That's what I was thinking, but I wanted to check.

On a clean SPARC system,

    PKGINST:  SUNWpng
       NAME:  Portable Network Graphics library
   CATEGORY:  GNOME2,application,JDS3
       ARCH:  sparc
    VERSION:  20.2.6.0,REV=10.0.3.2004.12.15.14.11

It looks as though this is installed in /usr/lib, so if I understand 
things correctly installing libpng from SFW should put a newer version 
in /usr/local. Let's hope the result isn't too sensitive to path 
misconfiguration.

There's a possibility that you've got more updates in your Solaris than 
I have. I'm using a set of CD-Rs that somebody in Sun marketing sent me 
which I find conveniently robust without a great deal of patching, I'm 
in no great hurry to raise my head above the parapet as far as 
Sun/Oracle are concerned :-)
