I had a similar problem with libdevice-usb-perl: it was built
successfully on all architectures except powerpc where it fails with the
following message:

--8<---------------cut here---------------start------------->8---
#   Failed test 'use Device::USB;'
#   at t/00-load.t line 8.
#     Tried to use 'Device::USB'.

I noticed that the shared object is not linked against libusb on
powerpc:

  cc  -shared -O2 -g -L/usr/local/lib -fstack-protector USB.o  -o blib/arch/auto/Device/USB/USB.so

On all other architectures a -lusb is included.

The same also happened for libogre-perl:

powerpc:
  g++  -shared -O2 -g -L/usr/local/lib -fstack-protector Ogre.o PerlOGRECallback.o PerlOGRECallbackManager.o PerlOGREControllerFunction.o PerlOGREControllerValue.o PerlOGREFrameListener.o PerlOGREWindowEventListener.o perlOGREGUI.o  -o blib/arch/auto/Ogre/Ogre.so 	\
	   -lOgreMain -lgio-2.0 -lcairo -lgobject-2.0 -lgmodule-2.0 -lgthread-2.0 -lglib-2.0  	\

amd64:
  g++  -shared -O2 -g -L/usr/local/lib -fstack-protector Ogre.o PerlOGRECallback.o PerlOGRECallbackManager.o PerlOGREControllerFunction.o PerlOGREControllerValue.o PerlOGREFrameListener.o PerlOGREWindowEventListener.o perlOGREGUI.o  -o blib/arch/auto/Ogre/Ogre.so 	\
	   -lOgreMain -lpthread -lgtk-x11-2.0 -lgdk-x11-2.0 -latk-1.0 -lgio-2.0 -lpangoft2-1.0 -lpangocairo-1.0 -lgdk_pixbuf-2.0 -lm -lcairo -lpango-1.0 -lfreetype -lfontconfig -lgobject-2.0 -lgmodule-2.0 -lgthread-2.0 -lrt -lglib-2.0  	\

Several libraries linked on amd64 and others are not linked on powerpc.
At a first glance these seem to be multiarch libraries (I only checked
libusb and libfreetype; ogre (linked on both amd64 and powerpc) is not
multiarch-enabled).
