So, a change like::
diff --git a/src/LaTeXFeatures.cpp b/src/LaTeXFeatures.cpp
index d5b8b2f..1f551b4 100644
--- a/src/LaTeXFeatures.cpp
+++ b/src/LaTeXFeatures.cpp

Before applying this, we would need to check why it seemed to work in some
cases. It may be, that some distributions have "undertilde.sty" and some
"undertilde.tex", the something like
\InputIfFileExists{undertilde.tex}{}{\usepackage{undertilde}}
should be used.
