--- Comment #1 from John T <jrt at worldlinc dot net> 2011-04-13 18:53:29 UTC --- On building all components of GCC 4.6.0 except java, ada and go, there was no problem installing with the prefix for 4.6.0 set to /usr/local. The problem seems confined to the java files for 4.6.0. I haven't tried installing any other version of gcc java to /usr/local.
