config/autorun.sh: running `/usr/local/bin/libtoolize --automake --copy --force' .ibtoolize: AC_CON

is caused by using CRLFs in Makefile.am. "m4" != "m4" and thus the libtoolize script will produce an error.


If you're using git, I strongly advise adding a .gitattributes file with the following:
*.sh     -crlf
*.ac     -crlf

*.am     -crlf
