Trying to install some cpan modules - dumper.so wrong ELF class???

Hi,

I need a few CPAN modules. For most of them I had no issue with a common
recipe, but I end up with issues on Net::SDP

here's my recipe :
SUMMARY = "Collection of Perl modules for working with shairport."
SECTION = "libs"
LICENSE = "MIT"
LIC_FILES_CHKSUM =
"file://${COREBASE}/meta/COPYING.MIT;md5=3da9cfbcb788c80a0384361b4de20420"

SRC_URI = "http://www.cpan.org/modules/by-module/Net/${BPN}-${PV}.tar.gz "

SRC_URI[md5sum] = "bb70cb8ebb7ca57c20ac134ac4499e66"
SRC_URI[sha256sum] =
"f43fa0f8f9705ae66a4084d13691c2ad7724b381424d368404c3d825bc5782f0"

require cpan.inc

and cpan.inc is :
S= "${WORKDIR}/${BPN}-${PV}"

inherit cpan

do_compile() {
export LIBC="$(find ${STAGING_DIR_TARGET}/${base_libdir}/ -name
'libc-*.so')"
cpan_do_compile
}

Here's the error message:

Can't load
'/media/yocto/var_yocto/var_yocto/rpi-build/tmp/sysroots/qemuarm/usr/lib/perl/5.14.3/auto/Data/Dumper/Dumper.so'
for module Data::Dumper:
/media/yocto/var_yocto/var_yocto/rpi-build/tmp/sysroots/qemuarm/usr/lib/perl/5.14.3/auto/Data/Dumper/Dumper.so:

/media/yocto/var_yocto/var_yocto/rpi-build/tmp/sysroots/x86_64-linux/usr/lib/perl-native/perl/5.14.3/XSLoader.pm
li

Does it ring a bell to anyone ???

Hi Yoctoers,

Anyone got any idea about this previous mail ?

I'd be willing to fix it, but I simply have no clue where to start :(

this is reaching out to native-perl mods there. seems its not cross
compiler friendly
look out for variables that are being used to construct path for
XSLoader.pm and use
the correct target paths

Actually, it seems that this package does not provide the regular .PL
file expected by cpan.
I found out a way to generate it, and I could compile. But as you can
see it uses perl native (I get an x86-64 build), and it's trying to
install on my / directory instead of the rootfs:

ERROR: Logfile of failure stored in:

FWIW, I can do the manual operations in qemu so it's really a matter of
using target perl instead of hosted perl I think :(

I'm investigating a little bit more or I will post additional
information for help :)

Thanks anyway,
Regards
Jay
