Comment (by ryandesign):

 Having both Homebrew and MacPorts installed on the same system will cause
 problems with some ports, so we don't support that. Please choose one
 package manager and uninstall the others.

 It looks like the error in the config.log is:
 {{{

 Consider adjusting the PKG_CONFIG_PATH environment variable if you
 installed software in a non-standard prefix.

 Alternatively, you may set the environment variables GLIB_CFLAGS
 and GLIB_LIBS to avoid the need to call pkg-config.
 See the pkg-config man page for more details.

 MacPorts currently provides glib2 2.78.4 so this should not be happening.
 You'll have to figure out where this glib2 2.16.2 is installed on your
 system.
