[tex-live] LZMA

[Karl Berry]

    There is a little problem with tug web-server and LZMA (at least for
    Darwin): it tries to assign to it extension txt which means that MIME
    type is not defined. Some users could find the task of removing
    extension and chmod-ing too challenging. May be it would be better to
    distribute binaries for LZMA in zipped form (together with the
    README)'

What url precisely is involved and where did you find it?  

What do you mean by "tries to assign to it extension txt"?  That your
browser on darwin wanted to save something as foo.exe.txt?
