configure: ** check for host type checking build system type... ../src/build-aux/config.guess: unable to guess system type This script, last modified 2010-04-03, has failed to recognize the operating system you are using. It is advised that you download the most up to date version of the config scripts from http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.guess;hb=HEAD and http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.sub;hb=HEAD This is usually fixed by updating gnuconfig; econf does that automatically but you can't use econf here it seems.
