Hi, just for the record, by chance it happened to me today and how I solved it easily:
GRASS 7.0.0svn (nc_spm_08_grass7):~ > r.stream.order stream_rast=streams@user1 direction=direction@user1 elevation=elevation@PERMANENT accumulation=accum@user1 stream_vect=streams horton=horton ERROR: Module built against version $Revision: 62395 $ but trying to use version $Revision: 63222 $. You need to rebuild GRASS GIS or untangle multiple installations. # Now simply re-run g.extension: GRASS 7.0.0svn (nc_spm_08_grass7):~ > g.extension r.stream.order WARNING: Extension <r.stream.order> already installed.
