st: xtabond2 mata

["alessia matano" <alexis.rtd@gmail.com>]

Hi ,

I have an original version of stata 9.1 and when I run xtabond2 with
mata, it says

xtabond2_mata():  3499  strtoreal() not found
                <istmt>:     -  function returned error

as mata option is not included in the xtabond2 package. I 'd like to
use it only to use orthogonal deviations...

anyone of you can help me??
thanks a lot
