Good guess Brice! This patch to configure from that nightly
snapshot gets it working again:

- --- configure.old 2011-06-17 11:01:25.000000000 +1000
+++ configure 2011-06-17 17:59:23.000000000 +1000

thus:

checking pci/pci.h usability... yes
checking pci/pci.h presence... yes
checking for pci/pci.h... yes
checking for pci_init in -lpci... yes
checking for pci_lookup_name in -lpci... no
checking for inet_ntoa in -lresolv... yes
checking for pci_lookup_name in -lpci... yes
checking whether PCI_LOOKUP_NO_NUMBERS is declared... yes
checking for pci_find_cap in -lpci... yes
checking whether struct pci_dev has a device_class field... yes
checking whether struct pci_dev has a domain field... yes

and it compiles and builds an lstopo which includes PCI info!

cheers,
Chris
