Upgrade the installed version of libtool - I fixed this in May:

Taken from pkgsrc/devel/libtool/patches/patch-ab:

----------------------------
revision 1.21
date: 2001/05/09 10:24:11;  author: agc;  state: Exp;  lines: +57 -7
If a tag has not been given, and we're using a compiler which is not one
of the ones with which libtool was built, attempt to infer the compiler
from the first word of the command line passed to libtool.

We only reach this test if libtool is about to die with a message about
lacking a specific tag, so this change is the least intrusive that can
be made.

This means that different CC options can now be recognised when compiling.

Bump version number to nb6
----------------------------

Regards,
Alistair
