Ok so I am installing bfgminer-git through yaourt now. I am now stuck at this point (see code below). Oh BTW I have been editing the PKGBUILD file to remove the opencl dependency and add the --disable-opencl flag to autogen.sh.
Running autoreconf -if...
configure.ac:12: installing './ar-lib'
configure.ac:9: installing './install-sh'
configure.ac:9: installing './missing'
Makefile.am:1: error: Libtool library used but 'LIBTOOL' is undefined
Makefile.am:1: The usual way to define 'LIBTOOL' is to add 'LT_INIT'
Makefile.am:1: to 'configure.ac' and run 'aclocal' and 'autoconf' again.
Makefile.am:1: If 'LT_INIT' is in 'configure.ac', make sure
Makefile.am:1: its definition is in aclocal's search path.
Makefile.am: installing './depcomp'
autoreconf: automake failed with exit status: 1
Is this something I should should be fixing on my system (such as a system variable?) or in the source code?
