This is what Gscreen uses to load halshow (note it loads the path from a preset
variable):
p = os.popen("tclsh %s/bin/halshow.tcl -- -ini %s &" % (TCLPATH,self.inipath))
So I would think you need to put tclsh before the path to halshow.
Not sure what happens without the INI path..
halmeter will show pin names.
