For a TeX label, nothing will happen. For an actually typeset metapost
string, you will get an error in the 'terminal' and 'log' outputs
because the font and its support files will not be present. These
are not fatal errors, so perhaps it does not bother you.

It is set out not to need a pre-existing installation of any kind of
TeX/MP, but it is vaguely possible that something crept in because
my system is littered with TeX and mp installations and at times it
is amazingly hard to keep autoconf 'localized'.

That's tricky; the build system is set up to create only a static
library at the moment, and it would require some autoconf jiggling
to switch to allowing .so creation as well. If that is important to
you, I can investigate, but that will take me some time.
