That makes more sense than my little hack disabling perl bindings.
I'll give this approach a try.

I tried it, but it didnt work.
configure.ac contains
AC_PATH_PROGS([PERL], [perl5.8 perl5.6 perl5 perl])
which is looking for
perl5.8
perl5.6
perl5
perl
Angstrom-1.3 build perl-5.14.2 so only the last check have a chance.
AC_PATH_PROGS searches for the first in the argument 2 list, which
can be found in the current PATH.
When I look at the "run.do_configure.*" of xfconf, the PATH contains
"<build>/sysroots/x86_64/usr/..." and
"/usr/bin"
but it does not contain
"<build>/sysroots/beaglebone/usr/bin"
which is needed to find the ARM perl.
Have no clue why.
There is already a dependency on "perl-native" in the recipe.
I tried replaced it with dependency on "perl",
but I still get the host PATH and not the target PATH.
I noticed that xfconf configure does not understand
"--with-libtool-sysroot="
added
EXTRA_OECONF += "--with-sysroot=${STAGING_DIR_TARGET}"
to no avail.
The tree in question was initially located in /home/X/Angstrom on i686
and moved to /home/Y/Angstrom on x86_64, and I manually
changed the environment file and conf files using
sed -i 's/X/Y/'
Maybe I screwed something up.
I am going to run ./oebb config beaglebone and rerun the build.
