this one makes my build fail:

[jolsa@krava perf]$ make
BUILD: Doing 'make -j4' parallel build

Auto-detecting system features:
... backtrace: [ on ]
... dwarf: [ on ]
... fortify-source: [ on ]
... glibc: [ on ]
... gtk2: [ on ]
... gtk2-infobar: [ on ]
... libaudit: [ on ]
... libbfd: [ on ]
... libelf: [ on ]
... libelf-getphdrnum: [ on ]
... libelf-mmap: [ on ]
... libnuma: [ on ]
... libperl: [ on ]
... libpython: [ on ]

... libslang: [ on ]
... libunwind: [ OFF ]
... on-exit: [ on ]
... stackprotector: [ on ]
... stackprotector-all: [ on ]
... timerfd: [ on ]

config/Makefile:335: No libunwind found, disabling post unwind support. Please install libunwind-dev[el] >= 1.1

...

LINK perf
