Relevant error message is here: cat /var/tmp/portage/sys-auth/libfprint-0.5.0/temp/aclocal.out ***** aclocal ***** ***** PWD: /var/tmp/portage/sys-auth/libfprint-0.5.0/work/libfprint-0.5.0 ***** aclocal -I m4 configure.ac:5: error: 'AM_CONFIG_HEADER': this macro is obsolete. You should use the 'AC_CONFIG_HEADERS' macro instead. /usr/share/aclocal-1.13/obsolete-err.m4:12: AM_CONFIG_HEADER is expanded from... configure.ac:5: the top level autom4te-2.69: /usr/bin/m4 failed with exit status: 1 aclocal-1.13: error: echo failed with exit status: 1
This was fixed upstream, so I went ahead and applied patch: http://cgit.freedesktop.org/libfprint/libfprint/commit/?id=43eca622cd49b58c87157e1ff1a2fcfdfba0934e
Thanks, Peter!
