GCC_DEFAULT_VERSION is set to 4.6 in ports/Mk/bsd.gcc.mk

Unlike some other default versions, it isn't setup to be able to be
overridden from make.conf

As Mark mentioned, some applications have a requirement for a specific
version of gcc, while others will specify a minimum version (USE_GCC=4.7+)

This is why you end up needing all of those versions. You may be able to
reduce some of the fragmentation by installing the highest version
first, then any app that can use that will, and only those requiring a
specific version will pull those in.

The root issue is that some apps will just refuse to compile on newer
versions of GCC
