  AIMS. To derive the mass profiles of the different luminous and dark
components in clusters. METHODS. The cluster mass profile is determined by
using the Jeans equation applied to the projected phase-space distribution of
about 3000 galaxies members of 59 nearby clusters from the ESO Nearby Abell
Cluster Survey. The baryonic and subhaloes mass components are determined from
the galaxies' luminosity-density profiles through scaling relations between
luminosities and baryonic and dark halo masses. The baryonic mass component
associated to the intra-cluster gas is determined using X-ray data from ROSAT.
RESULTS. The baryon-to-total mass fraction decreases from a value of 0.12 near
the center, to 0.08 at the distance of 0.15 virial radii, then it increases
again, to reach a value of 0.14 at the virial radius. Diffuse, cluster-scale,
dark matter dominates at all radii, but its contribution to the total mass
content decreases outwards to the virial radius, where the dark matter in
subhaloes may contribute up to 23 %, and the baryons 14 %, of the total mass.
The dark mass, and diffuse dark mass profiles are well fit by both cuspy and
cored models. The subhaloes mass distribution is not fit by either model.
