But does that account have the necessary permissions? Owning the
file/directory simply means that the owner permissions are used
(rather than the group or world permissions), but those permission are
necessary.

Also, the web-server account needs execute permission on all of the
parent directories.

You don't need to set $GISRCRC. GRASS itself only uses $GISRC;
$GISRCRC should only be used within Init.sh itself (the export is
gratuitous).
