Hi All, I upgraded the OS on the lap-top to Opensuse 13.2 and although Grass has been updated to the correct version for opensuse 13.2 (from geo repository) it fails to run generating “numeric, numeral or numpy not found.
Numpy is installed. This appears to be similar to an earlier issue with numpy not being found within a MacOS logged on 5th July 2014. Is this a general problem with the Opensuse 13.2 Grass 6.4 version or something specific to my machine?
