The LZMA compression packages are a patched LZMA SDK with the same 
zlib/stream patches used by mksquashfs (lzma-sdk-buildroot.tgz) and 
compressor/decompressor in the lzmatools-buildroot.tgz package.

They are not compatible with the lzma library and binaries from 
http://martinus.geekisp.com/rublog.cgi/Projects/LZMA and provided by 
the lzma-buildroot.tgz here in the same directory.
