RE gcc, I am read the link in the above email, and no answer to what fixes the chrome
error 
"usr/local/lib/gcc47/libstdc++.so.6: version GLIBCXX_3.4.18 required by /usr/local/share/chromium/chrome
not found"

I deinstalled and reinstalled *all* of gcc to try and fix it, and toyed with
libmap.conf.   If a fix is found with the latter rather than with ports,
I could write it into the libmap.conf here as a reference.

Additionally, is there some meta documentation about all gcc's 
versions to read, or some line in a file, which shows the minimum]
preferred one two or three GCC's to have installed for less trouble
building ports etc.

Thanks
