[Proj4j] Rotated latlon conversions

[Kees Kling]

Hi,

i'm currently working with a model who has a shifted poke grid

Output of wgrib:
 rotated LatLon grid  lat -35.600000 to 29.000000  lon -34.400000 to 
46.600000
 nxny 131544  (406 x 324)  dx 200 dy 200  scan 64  mode 136
  transform: south pole lat -30.000000 lon -15.000000  rot angle 0.000000

I need a tranformation from latlon to rotated latlon and I thought the 
trick would be
 >proj -v +proj=ob_tran +o_proj=eqc +o_lat_p=-30.0 +a=57.29578 + o_lon_0=-15
but this doesn't seems to work.
 
Can anyone gives me a direction

Thanks
Kees Kling
