Sean, thank you for your testing and feedback!

I have that message even with all Fedora 8 infrastructure ports. :-(

This seems to be a result of recent config changes of fontconfig and
should go away with new f8 ports.

I didn't see such a message with acroread7. Should try acroread8 to
reproduce it.

Those messages with _g[dt]k_ are not very informative...

I don't see this with acroread7.

Yep, fixed at linux_base-f8 REVISION=1. Thanks.

/me doesn't have any idea here, sorry.
