Eh. Yes,

It only happens for me with "g". With "perf record -af sleep 10" it worked.

It's up-to-date Fedora 14 on x86-32.

And there's no build output at all, except for the trivial:

[torvalds@eeepc perf]$ make
PERF_VERSION = 2.6.38.rc2.62.gec30f3.dirty
GEN common-cmds.h
* new build flags or prefix
CC perf.o
CC builtin-annotate.o
CC builtin-bench.o

so I have everything installed.
