This may or may not be the same issue.  In a case like this it
is always possible that one is missing the obvious, but right
now I am simply not seeing it.

Any chance to see where this dependency for lang/gcc47 on
itself is coming from?  Especially with the report that an
install followed directly by an upgrade triggers this?

Does this also happen if you do not have USE_GCC=4.7 in 

What exactly is the effect of that?  Does this not build
every other port with a dependency on gcc47?  If so, when
portupgrade temporarily remove gcc47, won't this impact
anything that portupgrade runs afterwards?


  pkg_delete: package 'gcc-' is required by these other packages
  and may not be deinstalled (but I'll delete it anyway):
  .. (depends packages ignore)

the key perhaps?
