[Libunwind-devel] building from git...

[Brendan Miller]

I'm not sure familiar with autotools, as I usually use scons... I
looked this up online, and it suggested these commands to generate the
configure file:

automake
aclocal
autoconf

but autoconf generates:

configure.in:20: error: possibly undefined macro: AM_PROG_LIBTOOL
      If this token and others are legitimate, please use m4_pattern_allow.
      See the Autoconf documentation.

./configure
configure: error: cannot find install-sh, install.sh, or shtool in
config "."/config
