This makes 'make perf-tarbz2-src-pkg':

[acme@...lia linux-2.6-tip]$ make perf-tarbz2-src-pkg
  TAR
[acme@...lia linux-2.6-tip]$ mv perf-2.6.35-rc4.tar.bz2 /tmp
[acme@...lia linux-2.6-tip]$ cd /tmp
[acme@...lia tmp]$ tar xf perf-2.6.35-rc4.tar.bz2
[acme@...lia tmp]$ cd perf-2.6.35-rc4/tools/perf
[acme@...lia perf]$ make
grep: ../../Makefile: No such file or directory
