Somehow I've ended up with 2 copies of gcc from ports in addition to 
gcc-3.4 in the base system. 

pkg_info suggests that only gcc-4.3 is needed:

  curlew:/home/mike% pkg_info -Rx gcc-4
  Information for gcc-4.2.5_20081126:

  Information for gcc-4.3.4_20090419:

  Required by:
  fftw-2.1.5_5

I'm sure I haven't chosen to install fftw-2.1.5_5, and pkg_info -R 
doesn't show any other ports needing it. I was wondering if I could 
safely deinstall fftw and both the gcc-4 packages but wondered if 
pkg_info only shows the run dependencies and not the build 
dependencies. I don't mind the disk space needed but portupgrade 
sometimes results in having to upgrade 2 copies of gcc which is quite 
time consuming.
