libc6-sparcv9v 2.5-0ubuntu8 (sparc binary) in ubuntu feisty

 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 and derivative
 processors. It only needs to be installed on machines using
 SUN4V Niagara and derivatives. If you install this on a machine without
 such chips, it won't even be used.
 .
 WARNING: Some commercial programs do not work well with these libraries.
 Most notably, IBM's JDK. If you experience problems with such
 applications, you will need to remove this package.
