Workshop fails with the error

fatal error: Glue::mkdirp("/./glue.gvest.haldane:0"): mkdirp() failed -- 
Permission denied
Exiting. exit code 2

This is most likely because the environmental variable
	DPGLUE_BASE
was set.  When the variable isn't set (default behavior) workshop
defaults to using
	/tmp
as the directory to create the socket directory glue.<userid>.:<display_number>.
So, glue.tsmith.:0 would represent userid tsmith on display 0.

Either unset the DPGLUE_BASE variable or set it to /tmp by issuing the command
	# DPGLUE_BASE=/tmp			(for sh/ksh shells)
	# export DPGLUE_BASE
or
	# setenv DPGLUE_BASE /tmp		(for csh)

To unset the variable so it uses the default behavior, type
	# unset DPGLUE_BASE			(for sh/ksh shells)
or
	# unsetenv DPGLUE_BASE			(for csh)
