[GSAS-II] conda install gives conflicts but no solution

[Lambert van Eijck - TNW]

Dear Brian,

On a new installation of ubuntu (and a fresh anaconda) I try to install 
gsas2:

[@ll:~]$ conda search  gsas2 -c briantoby

No match found for: gsas2. Search: *gsas2*

as you can see, it finds the two versions, but it's not very verbose on 
what the problem is, and bails out. There is no more feedback than the 
above text.

Previously I used the anaconda env + python to start/run Gsas2 and that 
worked. Is there a specific advantage/gain to debug the conda problem or 
can I do as I did previously?

thank you again, Lambert
