Thanks Martin, this was the push I needed.  I had thought the sparcv9 VIS probe stuff was it (red herring).

For anyone that might see this in the future, ghostscript-agpl (10.x) seems to bus error on sparc due to color management engine alignment issues (lcms2):

I would guess it does this on other (non-x86) ports too.

Someone was having similar issues a while back on HPUX.  Adding "-dUseFastColor=true” to gs args uses the older color management engine and bypasses this error.
