I just hit this when installing libtool on a MIPS box: ***** aclocal ***** ***** PWD: /var/tmp/portage/sys-devel/libtool-2.2.8/work/libtool-2.2.8 ***** aclocal -I libltdl/m4 configure.ac:26: error: Autoconf version 2.62 or higher is required configure.ac:26: the top level autom4te-2.61: /usr/bin/m4 failed with exit status: 63 aclocal-1.10: autom4te failed with exit status: 63 libtool-2.2.8{,-r1} should depend on >=sys-devel/autoconf-2.62, but in the ebuild they depend on >=sys-devel/autoconf-2.60.
ive fixed libtool-2.2.10 as 2.2.8 is dying. dont know why you've opted to install 2.2.8 on your system ... http://sources.gentoo.org/sys-devel/libtool/libtool-2.2.10.ebuild?r1=1.1&r2=1.2
