[GRASS-user] GRASS 6.4.0RC2 opening in X11

Hi folks

Something odd is happening. GRASS 6.4 (RC2) is opening with X11 rather than ActiveTcl. I get the following message in the OS X terminal after the usual opening:

GRASS 6.4.0RC2 (OSI1636):~ > wish8.5(17527) malloc: *** error for object 0x12d6d00: Non-aligned pointer being freed (2)
*** set a breakpoint in malloc_error_break to debug

Any idea as to what is happening?
