That is undesirable for reproducible builds. Most users have the default Xcode version for a give system, as Apple flushes all the updates that way. If users report broken builds and we recognize non-standard configurations, we encourage them to use the default version of Xcode for their system, and generally report that the default toolchain installation is the only supported configuration. Otherwise, chaos. > > Can you please indly point me to the place in MP base > where the value of configure.cc get decided? > /opt/local/libexec/macports/lib/port1.0/portconfigure.tcl
