Interesting. Building from a perf-tar-src-pkg tarball works:

$ rm -rf /tmp/krava/ && make install prefix=/tmp/krava
[...]
  LINK     perf
  LINK     libperf-gtk.so
  INSTALL  GTK UI
  INSTALL  binaries
  INSTALL  tests
  INSTALL  libexec
  INSTALL  perf-archive
  INSTALL  perf-with-kcore
  INSTALL  perl-scripts
  INSTALL  python-scripts
  INSTALL  perf_completion-script

but it breaks indeed the way you pointed out when building in-tree...

Having a look now.
