Begin autotools sanitization sequence by requiring ports to explicitly
specify which version of {libtool,autoconf,automake} they need, erasing
the concept of a "system default".
For ports-in-waiting:
USE_LIBTOOL=YES -> USE_LIBTOOL_VER=13
USE_AUTOCONF=YES -> USE_AUTOCONF_VER=213
USE_AUTOMAKE=YES -> USE_AUTOMAKE_VER=14
Ports attempting to use the old style system after June 1st 2004 will be
sorely disappointed.
There is a minor update to mtl. Since this is port only
consists of header, and no library is actually build I
followed their recomendation and added NO_BUILD which saves
some time doing unnecessary testing.
I also wanted to add LAPACK support but I couldn't. At least
I fixed a bug in configure in the process.
