 Why backport working solutions instead of releasing working solutions?
 > AFAICT this will only work if LFS is globally enabled/disabled in grass,
 as in grass7. The modifications done in grass7 are probably too
 fundamental to backport (not sure about libgis and the raster part, but
 for the vector part I had to change core functions in the vector libs).

 That would require backporting core parts of trunk. This won't be fixed
 for GRASS 6 and has been fixed some time ago for GRASS 7.
