Hello, I'm seeing this when I try to build perf in v3.9-rc7:
[penberg@golgotha perf]$ make CHK -fstack-protector-all CHK -Wstack-protector CHK -Wvolatile-register-var CHK -D_FORTIFY_SOURCE=2 CHK bionic CHK libelf CHK libdw Makefile:584: No libdw.h found or old libdw.h found or elfutils is older than 0.138, disables dwarf support. Please install new elfutils-devel/libdw-dev CHK libunwind CHK -DLIBELF_MMAP CHK libaudit CHK libnewt Makefile:673: newt not found, disables TUI support. Please install newt-devel or libnewt-dev CHK gtk2 CHK -DHAVE_GTK_INFO_BAR CHK perl Makefile:755: The path '/usr/bin/python-config' is not executable. Makefile:755: *** Please set 'PYTHON_CONFIG' appropriately. Stop. The problem is that I didn't have python-devel package installed and get-executable-or-default decides to error out instead of letting the Makefile disable Python support.
