liborc-0.4-dev 1:0.4.16-1ubuntu2 (amd64 binary) in ubuntu precise

 Orc is a library and set of tools for compiling and executing
 very simple programs that operate on arrays of data. The "language"
 is a generic assembly language that represents many of the features
 available in SIMD architectures, including saturated addition and
 subtraction, and many arithmetic operations.
 .
 This package contains the development headers and libraries, and should
 be installed to compile software that uses orc.
