A possible solution is to use the pvx files generated
through the `pvanal' utility. In this way you avoid
the gens-01 and skip the pvs analysis in csound.
You cannot use `mincer' and `pvstanal' anymore, but

  fsig1 pvsfread ktimpt, "pvxfile", 0 ;; chan 1
  fsig2 pvsfread ktimpt, "pvxfile", 1 ;; chan 2
  ;; optionally whatever pvs opcode that uses a fsig (also see pvslock)
  ...
  al pvsynth fsigout1
  ar pvsynth fsigout2
