I suspect that the problem is that -somersd- uses a pre-compiled Mata
function library. In order for Mata (and thus Stata ( and thus
-somersd-)) to use it, it first needs to add it to its index. However,
this does not happen automatically after you install a program with
-ssc-. The reason is that that would also clear the Mata (not Stata)
memory, which would be very un-stataish behavior for a Stata program
like -ssc-, though probably unproblematic in most cases. As soon as
you restart Stata, Stata will automatically index the necessary Mata
functions and -somersd- should run. Alternatively, you don't have to
restart Stata if you type -mata:mata mlib index-. Anyhow, if this is
the problem than this issue only bites in the Stata session in which
you installed -somersd-.
