aah, yes.

That gives:
ls: /libgrass_gis*: No such file or directory
g.version: error while loading shared libraries: libgrass_gis.so: cannot open shared object file: No such file or directory


Other checks show that $PATH and $GISBASE both survive.

So implementing the above script should fix this.
