I've done this, but I dont get results from calls within the GEOS library.  For example, my run of TestSweepLineSpeed gives (actually
lt-TestSweepLineSpeed):


  %   cumulative   self              self     total
 time   seconds   seconds    calls  Ts/call  Ts/call  name
  0.00      0.00     0.00        6     0.00     0.00  data_start
  0.00      0.00     0.00        1     0.00     0.00  run(int, GeometryFactory *)

Do you do something special to get a statically linked version of GEOS used?
