dbus 1.0 RC2 linker error

[Alexander Neundorf]

Hi,

I know this isn't the best list, but I think somebody who knows should be 
around.
So, dbus 1.0 RC2 doesn't link on my Slackware box:

Adding a "-lpthread" manually made it work for me.
It seems -lpthread should be added when linking libdbus.

That's what configure says:
