nautilus FTBFS on powerpc: automake1.5

[Matt Brubeck <mbrubeck@cs.hmc.edu>]

Nautilus fails to build from source on the powerpc autobuilder with the
following error from automake1.5.

Before I file a bug report, I'd like to figure out exactly what's wrong.
Why is automake1.5 being installed on the powerpc build machine?  Should
gnome-common depend on automake1.4?  Should nautilus Build-Depends:
automake1.4?  Or is this a configuration problem with the autobuilder?
