libc6-sparc64b 2.4-1ubuntu12.2 (sparc binary) in ubuntu edgy

 This package includes shared versions of the standard C library and the
 standard math library, as well as many others. This is the 64bit version
 of the library, meant for UltraSPARC systems.
 .
 This set of libraries is optimized for UltraSPARC-III and derivative
 processors. It only needs to be installed on machines using
 UltraSPARC-III 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.
