My version of GNU tar will do this very simply.  It has a -Pnn option
where nn is the number of path elements to strip off.  Although this
program was originally written to make tar archives under MSDOS, it will
also run under UNIX.  I use it on a Sun for precisely the task you
describe.

pdtar is available from the author for non-commercial, non-military uses,
in SCO Xenix, Ultrix, BSD UNIX, and MSDOS versions.
