better:

just "$PATH" will try to run it as a program.


I think Michael is correct, awk is fine, 

> v.db.addcol map=CondieHead layer=1 'columns=Elev varchar(10)'

I think this is the real error, not the missing awk.
note shell is csh not bash command interpreter, denoting the machine was
upgraded from MacOS <= 10.2.

/sw/ denotes a Fink install. Has it been removed but is still in the 
executable search PATH?? check ~/.cshrc file for fink adding itself to
the PATH.


> : awk required, please install awk/gawk first

Bug: that should read "v.db.addcol: awk required, please ..."
I've fixed this in CVS, repeated in many other scripts.

You can try 

GRASS> which awk

to test if GRASS can find awk.

also try searching the archives, we've seen this before IIRC..
