path to installed port's directory

[Igor Kolesnik]

Hi;

I'm makeing a port, let's say 'foo'.  It has a build dependency on a
port 'bar'.

In order to build 'foo' I need to know the installation directory of
'bar'.

In the foo's Makefile I can write

`pkg info -pq`/bar

I wonder if there is another, a better, way of getting that information?

thanks -- igor
