Further digging showed that vigra is built with corresponding
-Wl,-rpath=/usr/local/lib/gcc46 which makes it use correct libstdc++.
However, that rpath is removed by cmake on installation:

-- Installing: /usr/local/lib/libvigraimpex.so.4.190
-- Installing: /usr/local/lib/libvigraimpex.so.4
-- Installing: /usr/local/lib/libvigraimpex.so
-- Removed runtime path from "/usr/local/lib/libvigraimpex.so.4.190"

I have a fix for that:

http://www.freebsd.org/cgi/query-pr.cgi?pr=ports/176901

With it, no LD_LIBRARY_PATH will be needed, but USE_GCC=4.6+ will still
be required for ALL ports which depend on graphics/vigra as long as it
has USE_GCC=4.6+ itself.
