## NOTE: Any time tests fail here with an error like:
# Can't find a usable tk.tcl in the following directories:
# {$p(:26:)}
#
# $p(:26:)/tk.tcl: script error
# script error
# invoked from within
# "source {$p(:26:)/tk.tcl}"
# ("uplevel" body line 1)
# invoked from within
# "uplevel #0 [list source $file]"
#
#
# This probably means that tk wasn't installed properly.
## it indicates that something went wrong sourcing tk.tcl.
## Ensure that any changes that occurred to tk.tcl will work or are properly
## prevented in a safe interpreter. -- hobbs
