Using tex2Dbias in shader results in compiler error

I want to use tex2Dbias function described on Cg manual however I get a compiler error

Shader error in 'Custom/Cells': Program 'frag', function "ddx" not supported in this profile (maybe you want #pragma glsl?) at line 210

Shader error in 'Custom/Cells': Program 'frag', function "ddy" not supported in this profile (maybe you want #pragma glsl?) at line 210

Shader error in 'Custom/Cells': Program 'frag', function "tex2D" not supported in this profile (maybe you want #pragma glsl?) at line 210

I have

 #pragma target 3.0

set, so Cg profile is matching one required by manual, how can I fix that?
