Fixed in CVS, thanks.

Actually I don't include lirc_client as a dependency, that's something
rpm does automatically.
But i'm no rpm expert, so if there's any flag i can put in the .spec to
make it install even with some libraries missing, i would be glad to
include it (something like "%nonforce liblirc_client.so", you get the
idea).
There's a good reason for wanting to do this: plugins. For example the
mpeg plugin needs the rte library, but it shouldn't be a dependancy for
the main package. If rte isn't present, but the rpm is installed as is,
nothing bad will happen, the plugin will just be deactivated.

Nothing i can do here, i guess :-) [Well, unless it doesn't build
without rte, that's a bug, configure should disable anything necessary].

I would say some underlying lib (gdk-pixbuf?) was compiled with the old
png.h
