[oe] Python-dbus build error

[Thom Nichols]

Hello OE wizards!

I'm experiencing an error building python-dbus_0.83.0:

| Making all in _dbus_bindings

Which I think is referring to this arg: -rpath lib/python2.6/site-packages.

Now that path is the value of $(pyexecdir) which is defined as: pyexecdir =
${exec_prefix}lib/python2.6/site-packages  in _dbus_bindings/Makefile. The
command in the Makefile looks like this:
_dbus_bindings.la: $(_dbus_bindings_la_OBJECTS)
$(_dbus_bindings_la_DEPENDENCIES)
    $(LINK) -rpath $(pyexecdir) $(_dbus_bindings_la_OBJECTS)
$(_dbus_bindings_la_LIBADD) $(LIBS)

I also see other locations in the makefile where it uses:
$(DESTDIR)$(pyexecdir).  However, modifying the -rpath line to read -rpath
$(DESTDIR)$(pyexecdir) doesn't seem to help.

So it appears that all of $(DESTDIR), ${exec_prefix} and ${prefix} (one of
which I would hope points to
/home/tnichols/dev/oe/build/tmp/sysroots/armv5te-oe-linux-gnueabi in my
case) are all unset (or the empty string...)  I'm not a make expert; where
do these variables get set?  More specifically, since $(pyexecdir) is
defined as ${exec_prefix}lib/python2.6/site-packages, I'm guessing
${exec_prefix} is what I'm looking for.

Also, is this an openembedded bug or a python-dbus bug?

Thanks in advance for the help.
