libc6-sparcv9v2 2.10.2-3ubuntu2 (sparc binary) in ubuntu lucid

 Contains the standard libraries that are used by nearly all programs on
 the system. This package includes shared versions of the standard C
 library and the standard math library, as well as many others.
 .
 This set of libraries is optimized for SUN4V Niagara 2 and derivative
 processors. It only needs to be installed on machines using
 SUN4V Niagara 2 and derivatives. If you install this on a machine without
 such chips, it won't even be used.
