Hello list, I am trying to install aubio on my machine (Mac osx), I followed the instructions for necessary packages to be installed before aubio. It includes pkg-config. The problem is that when I run ./configure & make & make check before make install. The make check returns with follow error message. Making check in check make  check-TESTS /bin/sh: line 1: ./check-cflags: Permission denied FAIL: check-cflags /bin/sh: line 1: ./check-libs: Permission denied FAIL: check-libs /bin/sh: line 1: ./check-define-variable: Permission denied FAIL: check-define-variable /bin/sh: line 1: ./check-libs-private: Permission denied FAIL: check-libs-private /bin/sh: line 1: ./check-requires-private: Permission denied FAIL: check-requires-private /bin/sh: line 1: ./check-includedir: Permission denied FAIL: check-includedir =================== 6 of 6 tests failed =================== make[2]: *** [check-TESTS] Error 1 make[1]: *** [check-am] Error 2 make: *** [check-recursive] Error 1 ------------------------------------------------------------ If I ignore the errors and go ahead with aubio installation, after ./configure , it returns with error message like that checking for pkg-config... no checking pkg-config is at least version 0.9.0... ./configure: line 21348: no: command not found no checking for SNDLIB... configure: error: The pkg-config script could not be found or is too old.  Make sure it is in your PATH or set the PKG_CONFIG environment variable to the full path to pkg-config. Alternatively, you may set the environment variables SNDLIB_CFLAGS and SNDLIB_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details. To get pkg-config, see <<a href="http://www.freedesktop.org/software/pkgconfig">http://www.freedesktop.org/software/pkgconfig</a>>. See `config.log' for more details.  ------------------------- Kindly suggest how to make it all work ! regards, tania
