Sure. Many ports set DYLD_LIBRARY_PATH just for the testing phase.  
It's fine if a port sets it where necessary during the build. That's  
a temporary setting that doesn't live past that phase. But it's not  
fine for a user to set DYLD_LIBRARY_PATH e.g. in his .profile.  
MacPorts won't look in the .profile while building, but the product  
that MacPorts then built and linked with MacPorts parts might start  
using other parts as directed by DYLD_LIBRARY_PATH, and that's not  
what we want.
