There is a package undertilde.sty, but it is not included in TeXLive,
probably since it has no proper license:
http://www.ctan.org/tex-archive/macros/latex/contrib/undertilde
It is included in MikTeX, though.
The plain tex package undertilde-gen, on the other hand, which provides
undertilde.tex, is included both in MikTeX and TeXLive:
http://www.ctan.org/pkg/undertilde-gen
I have no idea if the could replace each other easily.
