Yes, you're right; there  is  no  ebuild  currently  in  gentoo.git  to  satisfy
`>=app-arch/upx-3.01[lzma]`.  However,  the  ebuild  maintainer  seems  to  have
realised this, and added the following entry to the tsmuxer ebuild:

        DEPEND="|| (
                >=app-arch/upx-3.01[lzma]
                >=app-arch/upx-bin-3.01
        )"

I.e., use EITHER `>=app-arch/upx-3.01[lzma]` (which doesn't currently exist)  OR
`>=app-arch/upx-bin-3.01`.  For now, you  will  just  have  to  use  the  binary
distribution with L.Z.M.A.\ support built-in,  until  the  source  release  adds
support for optional L.Z.M.A.

The binary distribution is also masked with all ~arch keywords, so you must  add
the appropriate ACCEPT_KEYWORDS entry for `upx-bin`.

        $ ACCEPT_KEYWORDS="~amd64" emerge -atvp --autounmask=y tsmuxer

        These are the packages that would be merged, in reverse order:

        Calculating dependencies... done!
        [ebuild  N     ] media-video/tsmuxer-2.6.11-r1::gentoo  527 KiB
        [ebuild  N     ]  app-arch/upx-bin-3.96::gentoo  452 KiB

        Total: 2 packages (2 new), Size of downloads: 979 KiB

        The following license changes are necessary to proceed:
         (see "package.license" in the portage(5) man page for more details)
        # required by tsmuxer (argument)
        >=media-video/tsmuxer-2.6.11-r1 SmartLabs
