I think you mean "liblzma" can help.

I plan to import liblzma into FreeBSD base system as
/usr/lib/liblzma.a and /usr/lib/liblzma.so (that may
change to /lib/liblzma.so), with the headers in
/usr/include/.  I expect xz to end up as /usr/bin/xz.

I'm not familiar enough with kernel development processes
to understand the implications there.

Cheers,

Tim
