Presumably this dependency was simply to ensure it was installed so Mesa drivers would support S3TC, and not an actual dependency of mupen64plus-video-glide64mk2 itself. libtxc_dxtn is now integrated in Mesa, so the dependency is unnecessary (presumably) and media-libs/libtxc_dxtn is being given last rites. Please remove the dependency.
It dlopen()s 'libtxc_dxtn.so' and uses it directly.
Dang. You are right. Looks like it already imports code from Mesa, so I'll submit a pull request upstream to pull the DXTn code into the project as well.
It seems that we can switch to bundled S3TC support. The code doesn't match libtxc_dxtn, so I'm not sure if it's exactly equivalent but I've just done minimal testing and things seem to work still. Let's give it a few days. Feel free to ping me to remove old version then.

Thanks. That'll switch from using the external libtxc_dxtn which implements S3TC to the bundled "S2TC" code. S3TC was patent-encumbered until a year or two ago, so someone created S2TC which avoided the patented parts but generated incorrect colors (if I understood correctly). Since S3TC is no longer patented, ideally upstream would replace the S3TC code with the code from libtxc_dxtn. But this works for my purposes :)
