It is not required - Ipe runs fine without it, and does not need it in
any way.  However, it is possible to write scripts that process Ipe
files in Lua.  The last paragraph in install.txt describes how to make
sure that the Lua interpreter can find the Ipelib bindings.  In
particular, Ipe comes with one script "ipe-update-master", which - being
a Lua script - requires the interpreter and requires the Ipelib bindings
to be installed as described in install.txt.

So, if your package installs "ipe-update-master", you need to require
the Lua interpreter.  Otherwise, "suggest" sounds right to me.
