Yes, these two ports conflict for the time being, and are properly
marked as such.

(And I am looking for a more elegant approach going forward, in 
particular when we move into GCC 5 territory where, based on input 
from Tijl and others, we now distinguish between lang/gcc5 and 
lang/gcc5-devel.)

Correct.  If lang/gcc49 or lang/gcc is installed, either of the
two is picked up; if a newer version is installed and USE_GCC=yes
or USE_GCC=X.Y+ are requested (and the installed version is newer),
that one is used.

Nothing to do with luck on your side, Mark.  Rather, design and 
implementation in the Ports Collection. :-)
