Forgive me Hamish, you are right. It should be "unable to open panel file: 
No such file or directory" like you say.

My finger had to slip when coping/pasting then.

Yes - but only if creating a new location from EPSG code! And this way I 
found the reson that d.barscale doesn't work: the PROJ_INFO file syntax is 
different when a location is set up via the Grass interface and when 
automatically generated from EPSG code. See this:

Via Grass set up:

unit: meter
units: meters
meters: 1.0

Automatic, from EPSG 2180:

unit: metre
units: metres
meter: 1

After replacing the automatic one with the Grass one d.barscale works fine.

Could there be any more commands which don't like the EPSG-generated 
PROJ_INFO files?
