The SELinux was a red herring, I simply hadn't understood the change in 
plugin technology. The current CVS version works for me on F7 under 
SELinux with the plugin built as described in the wiki.

Please try the CVS version at:

cvs -d:pserver:anonymous at r-spatial.cvs.sourceforge.net:/cvsroot/r-spatial 
login

cvs -z3 
-d:pserver:anonymous at r-spatial.cvs.sourceforge.net:/cvsroot/r-spatial co 
-P spgrass6

or a variant that works. The vector version looks OK, the raster version 
is basic (uses data resolution not window resolution, and only handles one 
raster at a time without categories).
