Ok, there is obiously an error in the package creation:
   /opt/csw/bin/pango-querymodules
is linked to isaexec and chooses the best ISA. This is wrong for this
kind of use. The isaexec should be removed and there should be two
binaries:
   /opt/csw/bin/pango-querymodules for 32 bit
   /opt/csw/bin/(sparcv9|amd64)/pango-querymodules for 64 bit
You can try this right now with
   rm /opt/csw/bin/pango-querymodules
   ln -s /opt/csw/bin/sparcv8/pango-querymodules /opt/csw/bin/pango- 
querymodules
Please tell me if that worked.

We may need /opt/csw/etc/64/pango for this

Why is that? A 32 bit app needs to pull in 32 bit libs and 64 bit apps
pull in 64 bit libs, but why should both ISAs be needed?

Is this really necessary on a per-app basis? Can't this be patched
into pango itself?

William, any advice on this?
