Can you give some more details? I can't replicate this problem so far.
What I did, in the gretl GUI (on Linux and OS X):


1) Open data9-12 (a monthly dataset)
2) From the Add menu, add log differences of the first 4 variables
3) Select Models/Time Series/VAR lag selection
4) Select the 4 log-differences as Endogenous, and accept all

   default settings
5) Click OK
6) Reasonable-looking results are shown
