Thanks Mel and Tim. I am trying to determine how much disk space the 
distfiles for a port would use. I can get the file size from the 
distinfo file in the port directory. So I need to list dependencies for 
which a distfile would be downloaded.

I guess my question now is which targets or variables need to be 
included to achieve that. (I know it includes build dependencies.
I didn't include build deps in the subject because I figured replies 
would give me the principle and I could expand from that.)

I took a guess at the existence of BUILD_DEPENDS and added it into the 
script. Running the modified script on multimedia/vlc I get the same 
number of dependencies as make all-depends-list so make all-depends-list 
is the same as make -V LIB_DEPENDS -V RUN_DEPENDS -V BUILD-DEPENDS for 
vlc. Is that all I need for any port?

thanks
