I had a look into this since it blocks SleuthKit and hence libguestfs.

The package has:

  BuildRequires: lzma-devel

However the sources also bundle a copy of lzma.  It appears at one
point there was the intention to delete the bundled copy of lzma, but
this code was commented out (before 2008).  So it in fact *always*
builds using the bundled copy as far as I can tell.  The BuildRequires
is spurious.

I thought that maybe it's now using the bundled copy because the
system copy is no longer available, but looking at the configure
output I don't see where it tests for lzma, so I don't think this is
the case.

Anyway the upshot of all this is that with the attached patch it is
possible to build afflib.  However you would probably need to get a
pass from FESCo to do this.

An alternative fix which I didn't explore is to use xz-devel.  However
it appears that the package somehow depends on a specific version of
LZMA (4.43) so I'm not sure if it will build with whatever version xz
supplies.
