I suggest switching to the 6.4 branch. Now that 6.3.0 has been
released, 6.3.x is stable (bug-fixes only), while 6.4.x is the
"normal" development branch (i.e. what the trunk was until recently).

7.x is the "radical development" version, where anything is up for
change. Once development actually starts on 7.x, it may quickly become
incompatible with previous versions of GRASS, and may require some
level of skill to even get it to compile.

You can.

	svn switch https://svn.osgeo.org/grass/grass/branches/develbranch_6
