We have had the Mac version of Primer running in Perpignan for
some time now. It can easily be compiled from the source which can be
ftped, with a few minor modifications in the primer.h file (i.e. you
must "#define SHORT" and perhaps, if I remember rightly, reduce the
limits of some of the "MAX" definitions). I would be happy to make
the compiled program available if the authors allow it in the future.
Don't hesitate to contact me if you have any questions.
