Ah, ah, this is our problem.

We have a rpath set in HOST_LDFLAGS, but this variable doesn't seem to
be used when building host-libxml-parser-perl. However, by
Expat/Makefile contains LD_RUN_PATH="/opt/outputs/perl/host/usr/lib" in
the environment when calling ld:

LD_RUN_PATH="/opt/outputs/perl/host/usr/lib" cc  -shared -O2 -g -L/usr/local/lib -fstack-protector Expat.o  -o ../blib/arch/auto/XML/Parser/Expat/Expat.so 	\
	   -L/opt/outputs/perl/host/usr/lib -lexpat

And LD_RUN_PATH is used by ld as the RPATH when no -rpath option is
used. I guess this LD_RUN_PATH is set because we run the Makefile.PL
script with INSTALLSITELIB=/opt/outputs/perl/host/usr/lib/perl.

Could you post the output of:

rm -rf output/build/host-libxml-parser-perl*
make

Thanks,

Thomas
