dependencies rebuilt unnecessarily

[ssen@…]

port install foo will often rebuild dependencies unnecessarily if foo has a dense dependence tree. For example, if you have port A depending on B and C, and B depending on C, C will get rebuilt twice (!!!). For complicated things like qt3 and XFree86, rebuilding is not acceptable.

The attached test.tar.gz has 3 fake ports of this fashion. If you do "port install A": ---> Fetching A ---> Verifying checksum for A ---> Extracting A ---> Fetching B ---> Verifying checksum for B ---> Extracting B ---> Fetching C ---> Verifying checksum for C ---> Extracting C ---> Configuring C ---> Building C with target all ---> Installing C ---> Cleaning C ---> Configuring B ---> Building B with target all ---> Installing B ---> Cleaning B ---> Fetching C ---> Verifying checksum for C ---> Extracting C ---> Configuring C ---> Building C with target all ---> Installing C ---> Cleaning C ---> Configuring A ---> Building A with target all ---> Installing A

This is clearly not desirable

port A, B, C
