Hello Chris,

I wanted only to discuss about a method to find missing dependencies. 
Then I thought a little bit and I decided it would be the best to use a 
naked system. That means no ports installed. The reason why I am using 
pkg_delete \*. Then to install via make a port and see what happens.

Now then I was making libXft something interessting happened. The cached 
tbz port of libXft didn't needed the existence of Xrender.h 
(xorg-libraries), but the make install needed xorg-libraries. After 
creating a tbz-file it wasn't needed anymore.

I don't know if the xorg-libraries is a missing dependency or not? I 
would think, yes, because without it will not build. But when it is 
build the dependency is not needed in the Makefile.

The next thinking problem is:  I found many ports (I am running a build 
server) which needs xorg-libraries to be compiled. But they are normally 
running under X and to run X you will install xorg-meta-port. That 
brings me to the question: is xorg-libraries a missing dependency for 
audio/nas? Because without xorg-libraries it will not compile or is it 
not because , if you want to run you need xorg?

I was only searching for a way to control if a port is running. Becauxe 
you have no pointyhat, I had to do it on a naked (no ports installed) on 
a build server for each package separately. But cached packages are for 
this sort of debbuging not good, they will not clarify if another user 
will get no problems...
