Perhaps you should add the directory containing `libgtkhtml-2.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libgtkhtml-2.0' found

your libraries are in a nonstandard prefix so pkg-config can find them.

But after that i installed libgtkhtml-3.0.0 tar successfully but still it is 
giving same problem.
So i don't know how to adjust PKG_CONFIG_PATH .
And also even after installing libgtkhtml also why it is giving same 
problem.
If anybody knows plz help me.

Thanks in Advance
