liboil0.3-dev binary package in Ubuntu Precise i386

 Liboil is a collection of functions that often benefit from having
 special implementations on various architectures or CPUs. Each function
 in liboil has several implementations which may perform faster or
 slower on a given CPU. Some implementations use alternate algorithms,
 some use hand-crafted assembly, and some use special instructions that
 are only available on certain CPUs, such as MMX, SSE, or Altivec.
 The fastest implementation is automatically chosen at runtime.
 .
 This package contains the development headers and libraries, and should
 be installed to compile software that uses liboil.
