[Met_help] Troubleshooting test cases with MET 2.0

[Remi Montroty]

Hi,

I am trying to make sure MET v2.0 installed properly.

I seem to have a problem with test_mode.sh  as follows:
[met at cipsproc3 scripts]$ ./test_mode.sh

observation ***

The fact that the convex_hull function fails seems problematic. What 
should I look into?

Thanks!
