libnids 1.23_1 build failure due to libtool 2.2.6a_0 updated

[sck@…]

On my 10.5.6 host with MacPorts-1.7, I came across the following error (and fix) today...

Biko-2:~ sck$ sudo port selfupdate

MacPorts base version 1.700 installed
Downloaded MacPorts base version 1.700

The MacPorts installation is not outdated so it was not updated
