  We consider the resummation of soft-gluon emission in the transverse-momentum
distribution of vector mesons in hadronic collisions. We find that the resummed
expression in the impact-parameter formulation has an expansion in $\as$ with
factorially growing terms with oscillating signs. These diverging terms arise
from the small impact-parameter region of integration, and are of a subleading
nature. We also obtain a closed expression for the next-to-leading logarithm
resummation in $\qt$-space, and we study its analytic structure. We find in
this case that, although no factorially growing terms are present, there are
geometrical singularities that severely restrict the range of applicability of
the resummation formula.
