Nikolas,
   looks like a bug, in numpy 1.4 on mac ppc too. Use dot instead --

import numpy as np

x = 1j * np.ones(( 2, 3 ))
y = np.ones( 3 )
try:
     print "vdot:", np.vdot( x, y )
except ValueError, e:
     print "ValueError:", e
print "dot:", np.dot( x.conj(), y )


numpy core/numeric.py has
     from _dotblas import dot, vdot
but I don't know how to use testing/... for blas,
nor how to log a ticket -- experts please advise ?

cheers
