[GRASSLIST:4198] Re: Adding CATS to buffered lines (Grass5.7)

[Craig Aumann]

How new?   I'm running on Red Hat Enterprise 3.0. 

[root at landscape installs]# rpm -q grass
grass-5.7.0-1

I've just looked at the online binaries, and I think I have the most
recent RPM installed.   

Am I going to have to compile from source?

Cheers!
Craig
