Otherwise the packages would not be accepted as they could not be built using the official builders which use exclusively packages available in the distribution itself. In this particular case though I have updated some tools to versions from RHEL7 or Fedora so I am using:

With the exception of libtool (I can never get the hang of libtool), I don't believe any of those packages are needed to compile from a tarball of NUT.

Looking at the backtrace, though, I think that NUT is only including AC_PROG_LIBTOOL, so it seems like that version of libtool and autoconf are not compatible. (On Fink, I am currently using autoconf-2.69 and libtool-2.4.6)

At some point, we took out a call to usb_set_altinterface() - the kernel is supposed to activate bAlternateSetting=0 automatically, and re-selecting it caused problems on other platforms. Maybe it was required with Linux kernel 2.6.x. With libusb-0.1 linked in, does "-x usb_set_altinterface=0" change anything?
