is macports getting rusty?

Actually building rust does NOT take that much longer than any other 
compiler tool kit, such as gcc or LLVM(clang) . This is in part because 
rust itself is based on LLVM and internally the build compiles its own 
LLVM instance before going on to build the rust specific parts on top of 
that. This accounts from probably something like 60-70% of the total 
build time.

If you find yourself during an port update building rust from source, 
either just let it finish, or if you don't want your machine tied up 
building rust for some period, just cancel the build and try again later 
on, as as others have pointed out eventually the buildbots will provide 
the binary tarball for it and thus you will just pick that once its 
available.
