[GRASS-dev] standalone installer cleanup

[Hamish]

Hi,

re. r57342, the PROJ_LIB variable is needed by e.g. cs2cs used by some scripts, and I'm not sure if the removal of tcl/tk from the PATH was intentional or just an over-merge, but fwiw a functioning gis.m should remain as an alternative in case there are multiple-python install problems (as ongoing) or just because someone likes to use it for whatever reason.


thanks,
Hamish
