Hi,,

 I have a new clean Leopard install and macports (1.5.0 - 10.5) and my first port install sipcalc show this warning:

$ sudo port install sipcalc

Warning: Please fix or indicate this misbehavior (if it is intended), it will be an error in future releases!

 The program runs perfectly, but a write you to inform you of the warning.

 Thanks for your work.
