I appologise. The file does exist on the other 2 ia64 boxes:

% nm /usr/lib/liblzma.a | grep physmem
hardware_physmem.o:
0000000000000000 T lzma_physmem
                 U lzma_tuklib_physmem
tuklib_physmem.o:
0000000000000000 T lzma_tuklib_physmem
%

sorry about this, I looked in the wrong place.

I rechecked this again, seems correct.
