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

[JC <jc@vtkloud.com>]

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'

/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 ???
