Upgrading freetype can have "interesting" and unexpected results. Scribus might be compiling against the new freetype, but getting linked against the old one - with a fairly high chance of it going "splat". Alternately, it might be linking to the new freetype, but one of the libraries it uses may link against an older one - also potentially causing some unpleasantness.
I’ve had relatively few problems with installing a new Freetype on my systems when necessary, but I tend to build a new Qt against it too.
I have my Solaris 10 images now, it’s just a matter of getting around to installing them. I don’t suppose Solaris 10 would be compatible with Linux’s LVM or anything as unexpectedly and spectacularly useful as that?—Craig
