## 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 occured to tk.tcl will work or are properly
## prevented in a safe interpreter.  -- hobbs
