-pantest2- (remember the dashes!) works perfectly on Intercooled Stata 9.2 fully updated.
Dynamics methods usually report a test for autocorrelation. Unfortunately, they are random effects methods.
Given that T is almost equal to N, my suggestion is to use -xtpmg- from SJ7-2 (you can also test if autocorrelation is really a problem).

Thats really strange since I always have tsset my data! Is this a general problem with this command or may it be caused by my Stata Version?
