Should I open an issue upstream perhaps, even though developments have taken place about 3 years ago?

i think TMV is a library that was used by a package we don't include any more, what depends on this?

[Athanaseus]

GalSim uses this.

From docs it says: GalSim can use either Eigen or TMV for its linear algebra routines. https://github.com/GalSim-developers/GalSim

[gijzelaerr]

galsim is not that important, so nice to have but otherwise we can drop it. you could try to get it to work with eigen.

[gijzelaerr]

lets just drop this package, we don't need it anymore.
