libc6-vfp 2.9-20ubuntu2 (armel binary) in ubuntu karmic

 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 to use a VFP coprocessor, and will
 be selected instead when running under systems which have one.
